Gentlemen:

I removed the head cover from my GCV160 and discovered that at TDC the intake valve lash was over 0.040". Exhaust measured at 0.006". I am uncomfortable simply setting the lash to spec and putting the machine back together, and would appreciate guidance.

Background: I bought a new Karcher pressure washer equipped with the GCV160 engine. It now has 40 hours on the engine. Changed oil at 5 hours. Oil level good. But one day the engine would not start. Good spark, but discovered zero compression.

So I pulled the head cover. Discovered the intake valve was not moving freely. Valve stem covered with goo that looked like typical gasoline varnish. My fault. I suppose I left gasoline in the engine and it got stale.

I sprayed carb cleaner on the stem and the valve immediately began to move freely. Finger over the plug hole indicates compression is now there. But there is huge clearance between the intake valve stem end and the rocker arm of 0.040".

I wonder what might cause the strange lash readings. It sounds like there is metal to metal contact so the intake valve appears to be seating. But something is not right. Any ideas and guidance would be greatly appreciated.

Thanks, Bill

Hi Bill, I have one of these engines. I have not been in it too much internally, just to check the valve lash. This is an OHC engine. The cam I think is plastic. There must be an issue with your camshaft albeit an odd one for sure. .04" certainly is cause for alarm. I would start by checking the condition of the rocker on the Intake and the camshaft itself. You may need to verify the valve is seating and nothing is amiss there. Please repost and let me know what you find!
I just finished reading in a forum where a guy had one that the adjusting nut for the lash stripped the threads . They determined it to be a factory defect; so it will be quite interesting once the cause reveals itself.
There could be a problem with the valve spring as well.

ShotOut: Thanks so much for the response. I checked the cam and it appears OK. I have decided to order a new rocker arm to see for sure whether the existing one is bent. If it's not, sounds like you would suggest dismantling the machine to inspect the valve seat, rather than simply adjusting the lash to spec and trying to fire it up. Correct? Thanks, Bill

Reply: Strange Valve Lash Readings Hond...

Hi Bill, I agree. Try setting your valves to spec. A bent valve that got bent from sticking could cause a large lash as well. If it will not run, then maybe remove the rocker cover and inspect that whole valve train real good. I suppose a rocker arm on these engines could get bent too.
bill70j
Reply: Strange Valve Lash Readings Hond...

bill70j

Very well. I have adjusted the lash to spec, but doing so took up almost all of the adjustment travel.

I have just ordered the new rocker arm. Once it gets here, if I find that the existing arm is bent, then I will install the new one, readjust the lash and should be good to go.

If the existing arm is not bent, then I will dismantle the machine and have a close look at the valve and seat.

Thanks again for the advise. I'll report back shortly.

I already received a new intake valve rocker arm in the mail today.

Recall that I had previously set the valve lash to spec with the old rocker arm, which I thought had been bent.

So took the old one off, replaced it with the new one. And it became immediately obvious that the old rocker arm was not bent.

So I don't know why I have developed a mysterious 0.040" valve lash. I am going to make up a temporary paper cover gasket, put the machine back together, fill it with oil and see what happens.

It the engine starts, I imagine it will kill itself in short order. I'll be back in there either replacing a broken rocker arm, resetting the valve lash, or who knows what else.

I'll report back tomorrow.

Thanks again ShotOut, for all of your help. I have just had a partial success.

I reinstalled the head cover and temporary gasket, filled the machine with oil, and fired the thing up. The following is what happened. Would appreciate your thoughts.

Are these symptoms consistent with what you're thinking is the problem? Or could I have another unrelated fuel delivery problem?

1) Closed choke
2) Pulled the started rope 10 times - nothing
3) On the 11th pull, a whimper. I'm excited
4) On the 12th through the 30th pull, it runs for 2 seconds at about half speed, then dies
5) On the 31st pull, it keeps running, though at half speed. Now I'm really excited
6) I let it run for 2 minutes for warm-up, then close the choke. Stops firing. I immediately open the choke again and it resumes running, again at half speed
7) I repeat #6 several more times and the same thing happens - the machine will only run at half speed, and dies when I open the choke.

Is my next step to pull the head and find out what the valve guides, valves, and seats are telling me?

Thanks again. I truly appreciate the help.

Regards, Bill

Hello again Bill, You are certainly welcome. Thanks for keeping us posted. I know that the Honda carburetors are quite finnicky and need to be squeaky clean to work properly. It ALMOST sounds like a fuel system problem. BUT..... I have gone back and read your first post, and think the Intake Valve is creating the issue. If the machine runs at 1/2 power, the Intake valve may be slightly bent and not seating completely. Only running at choke and dying when you open the choke indicates a BAD LEAN fuel condition. It is not getting enough fuel to keep running without being choked. A compression test is not real informative because these engines have a compression release mechanism built on the camshaft. They can go bad, but it is a little rare. If one WAS to go bad, the symptoms would be quite similar with what you are experiencing because the compression release holds one of the valves slightly open on the compression stroke (likely the Intake valve). If your fuel filters are good, and the carb is not dirty....then a bad Intake valve or malfunctioning ACR (Automatic Compression Release) would likely be the culprit. Why not maybe pull the cylinder head if your fuel system is OK and have a GOOD look at that Intake Valve. When you initially sprayed that valve stem with carb cleaner, you may not have gotten ALL the goo off of it. There could be some more further up the stem and inside the valve guide as well. An Intake valve partially sticking open would create a BAD LEAN condition. Let me know what you find. I will be here.
Just for your info regarding the valves and timing; On the bottom of the cam, there are two lines that should line up with the edge of the valve cover sealing area, and the keyway on the crank is perfectly perpendicular with that line, that is how you check the belt timing.

Thanks again for your great advice. I am going to pull the cover this morning and see what the lash looks like on the intake valve. If it's still to spec, then I'll go right to the carb.

If the intake valve lash is 0", and then some, that may indicate trash is clearing from the guide, stem, and seat, No?

The timing should be set properly, as the marks on the bottom side of the cam line up properly with the housing.

Thanks again for your help. I'll do some stuff today and post findings.

Regards, Bill

I pulled the head cover this morning and found the lash settings still to be right on spec.

So my next move will be to pull the carb and see if there is anything strange there. If not, it's off with the head.

Hi bill70j This OHC engine does not actually have a head. I initially thought it may but it is a different design than a regular OHV motor with pushrods. The case splits in two at an angle, so everything you have seen and inspected so far is pretty much all there is to the top end. The case would have to be split and the piston removed to observe the valve seats. The stems and guides though, you can access under the rocker cover. There is no head to remove. I know because I wanted to remove the carbon from the piston on one I am currently working on, but would need to split the crankcase to do so.

Bill, Have you split the case and examined the Intake valve for straightness, seating and smooth operation in the guide? Let me know. Here are all the valve train parts. Note that the Cam Lobes are on the Camshaft pulley and not the Camshaft itself. Ingenious design.

Question: Honda GCV160 Suddenly Burns Oil

egumpher

I have a Husky pressure washer with a Honda GCV160 engine. I regularly change the motor oil. The engine started to burn oil at rate of about 1/4 quart every hour of operation. I've rebuilt many small engines in my day and will order replacement valve seals and piston rings. Since I don't have a service manual for this engine and therefore don't know the proper torque values to split the case I will change the valve seals first to see if that fixes the problem.

Is there a service manual available with torque values and other important information for the GCV160?

Thank you and best regards

Question: New Carb Leaking

I just replaced the old carburator and gaskets on a honda gcv160. Now when I turn the gas line on, it leaks gas at about an ounce or two a minute. It is hard to see where it is coming from. It doesn't seem to be the gas line, and it looks like maybe closer to the air filter than the motor.

What did I do wrong?

The experts say that your float valve is stuck in the open position allowing fuel to run out of the top of the carb. I had the same problem with a NEW carb

It only takes a small piece of debris to hold that needle valve open. You will need to drain the fuel system, remove the bowl, remove the float and needle assembly and flush the cavity where the needle valve seats. Try that and post back if needed.
Kill switch wire broke. Wondering (before I pull it apart) where the end mounts (not the switch end)? Engine runs but have to "stall" it to shut down...

Question: Honda GCV Won't Start

1148191

Last year I bought Black Max power washer and used it for 1 hour. I cleaned it and stored it in my heated basement over the winter. I used it again yesterday and after about an hour the washer started to lose power before the engine stopped running. I tried pulling the starter cable and the recoil was really hard. I had vented the wand so there was no pressure in the power nozzle. I checked the plug and it was black with heavy carbon. I cleaned it and reinstalled it but the engine will no longer start and the power required to pull the cord it excessive. I called Black Max and they told me to call Honda. I called Honda and they said to call an engine repair shop. Any ideas before I do that?

Thanks.

THE CAM PULLEY IS BROKE. SAME PROBLEM I HAD. THIS IS A COMMON PROBLEM OF THIS ENGINE.
Home Depot has a lawn mower with the Honda GCV160 Electric start version engine. They also have a pressure washer with the Honda GCV160 engine. I have a disability that makes it difficult to pull the starter rope. I would like to get the electric start on the pressure washer. My local Honda bike shop service center said they use different blocks. Can I get a pressure washer pump mounted to the Honda GCV160 Electric start version engine? If necessary, are there adapter plates that can be purchased or manufactured for this application?

I have a Husky pressure washer with a Honda GCV160 engine. It is about two years old anf has been used very little. Last Fall I used it and the engine ran"lumpy" hunting RPM, low power. I drained the fuel, ran the carb out and put it in the barn. LAst week I filled the fuel tank and have trouble: It starts on full choke but as soon as I move the choke the slightest bit the engine coughs and dies. Took the carb off cleaned all with Berrymans, blew out passages, visually checked orfices and float/valve. All look fine carb is spotless but same problem. Also checked fuel tank filter and hoses and shot off valve, fual fills carb quickly.

Any ideas? Thanks, bob

[QUOTE=gerryrigger;70280]How challenging is it to replace the coil assembly on my honda gcv160 engine? It is used on a lawn mowe."

Very easy. On a scale of 1 (no effort) to 10 (tough) it's a 2. Just did it today along with quite a few other replacements (carb, gas tank, starter pulley, etc.) on a GVC160 that caught on fire. The key is to use the shadow (clean spots) beneath the mounting bolt heads to position it corrrectly before you finally tigthen it down. Then turn the flywheel to make sure the flywheel and coil aren't in contact.

Good luck.

A correction. I had a used coil from another gcv160 which had marks from the mounting bolts from the previous installation. Your new coil won't have them, so measure the gap between the flywheel and the coil before your remove your old coil and use the measurement to position the new coil. Then turn the flywheel to make sure the flywheel and coil aren't in contact.

Your carb is intentionally set very LEAN to meet current EPA emission standards. You can try to bore out the main jet with a torch cleaning kit, so it will pass more fuel. Be careful doing so, you do NOT want it to pass TOO MUCH.

My GCV 160 used on Campbell Hausfeld pressure washer won't start. New in 2002. Religiously maintained.

Reply: GCV 160 Won

The carb float is made of plastic, and the needle and seat fits poorly as well. The stable and Star-tron will distort the float over time. Try pulling the float out, drop it in either water or gas, to check for a hole in the float. Also, remove the needle valve, blow through hole with air pressure.
If that heals it, try to empty the carb of fuel after using, and drain the tank if to be unused for more than a month. Good luck.

I have owned a lot of lawn mowers over the years. The Honda GCV160 engine on the Lowes Troy built model 11A-542Q711 lawn mower is the worst engine I have seen. Since brand new the engine burns rich (black smoke emits from the exhaust). The spark plug fouls up after approximately 15 minutes running, causing the engine to stop.
