Hello 1279348,

The part number 530095854 Cutting Head Assembly is threaded on the spindle with a left hand thread. You will need to stop the spindle from rotating while you thread the trimmer head off.

I tried to screw the head onto my WT3100 weed eater and it would not thread on. It felt like I was threading a metric nut over an american standard or visaversa

Hello Biklover52,

I also tried to assemble the 530095854 Cutting Head on to the 530071584 Gearbox. And it would not thread on for me either, until I figured out it is a left hand thread.

Question: Wt 3100

1194258

I currently have a Weed Eater WT3100 that runs briefly when cranked the stutters and dies as if it was sarved for fuel. To date I have replaced the carburetor,all fuel line, in tank fuel filter and removed the mufflerto check for excessive carbon buildup. The newly installed primer bubble performs as described in the ereplacement parts online viedo.(bubbles from the return line in the tank) Fuel is visible in all lines.

Any suggestions for a fix would be greatly appricated

Hello jocur69,

I have checked with the manufacture and the pulley housing assembly part number, 530014009 has not been replaced by a new part number. You might want to keep searching on line for the housing and contact one of the may Weed Eater service centers around the country to see if any are available.

Question: Adjustment Tool

Shadowhawk

On my WT3100 weed eater there are adjustment screws for the air and fuel mix. These screws are not slotted for a screwdriver but are round and knurled on the outside. There must be a special tool needed for this adjustment. Do you supply it and what is cost and availability please? Thanks
I ahve a very difficult time replacing fuel lines in the fuel tank due design constraints.

Wadster

Home Depot & Lowes sells a fuel line & primer line kit made by Ryobi. It cost about $7.00 and comes with a curved wire tool. The wire has a ring on one end and a small hook on the other. Once you have the old lines off, just fish the wire thru the holes and out the screw cap end, attach you new line and pull it thru the hole.... I've used the tool for many fuel line projects on 2 cycle engines.. Hope this helps & good luck, Jerry

I can't figure out how to remove and replace the cutting head of my wheeled Weedeater WT3100. Do I need a narrow wrench to get the nut loosened?
UtahAV
Reply: Wt3100 Cutting Head

UtahAV

Hi eudorafrank,

There is a small opening between the gearhead and the dust cup. Inserting a small metal object such as an Allen wrench or a small screwdriver will lock the spindle from spinning. Then you can unscrew the trimmerhead from the spindle. The head uses a reverse thread.

I hope this helps,

Question: Carb Adjustment

ternandes

My trimmer will only run at idle. I can't find information on carb adjustment. Is it safe to assume that if I buy a whole new carb, it will not need much adjustment, or will come with instructions? I have adjusted my present carb within the limits of the limiter caps, and no help. the owners manual says to take it to a repair shop, but I suspect it won't be worth the cost... and likely they'll just replace the carb. I can do that myself.
UtahAV
Reply: Carb Adjustment

UtahAV

Hi ternandes,

If the trimmer had been running well and then started having issues it is unlikely that the problem can be solved with an adjustment. The problem is likely due to dirt or other debris in the carb. You can replace the carb or try cleaning it. A new carb will come set from the factory to operate at sea level. Minor adjustments may be needed to tune it for your location. It is best to have a shop tune the carb as you can damage the engine if you are not sure how to make the adjustments. The shop will also have the special tools needed to make the adjustments.

If you want to try cleaning the carb we have an article and video that you might find helpful. You can view it here..

If the unit has been used regularly, it may be a exhaust port blockage of carbon. Remove the muffler, and look inside the hole, If you see lots of puffy, black stuff- simply scrape it out with something that won't scratch the port opening...Like a pop-sicle stick or wooden pencil.. If there is carbon build up you may want to clean your muffler also.. But make sure if you clean the muffler with something flammable (which that's ok).. just be sure to rinse it well and let the muffler dry.."NO FLAMES" !! Hope this help with rev up situation..

Question: Fuel Blockage?

Scott

Hi, My WT3100 has worked perfectly for 5 years until a month ago when it started needing richer mixtures (I had to keep choke on half) and finally cut off after the first 5 minutes with the bulb not refilling. Is this due to a fuel filter problem? Or is it due to a faulty carburetor? It would cost at least $60 labor plus parts plus tax to have it fixed; is it a big job or can I do it myself? I hate to throw it away purely because it may be only a bit more expensive to buy a new unit.

Starter rope stays out of machine and does not recoil back. I have taken it apart several times and rewound rope but happens shortly after. What do I need to replace? Is it the entire coil and rope assembly? Is it prewound for the correct amount of tension?

Question: Fuel Tank Connections

Bob

On my wt3100 fuel lines are squeezed through holes in bottom of fuel tank. Have they come up with better connections possibly on a universal type tank? Or by purchasing and installing new fuel line kit correct? The old lines were shot, tried to work with what I had, ran good but leaked.

How does the cutting head come off of the Weed Eater WT3100? Does it unscrew and what do you hold to unscrew it?

Reply: Replacing Cutting Head

Skip

Leonard if You look very closely above the cutting head You will See there is a groove cut in the side of the aluminum housing. If You turn the head while turning it You will see there are also holes in the shaft so You can slip something like an allen wrench into it and it locks the shaft. While holding the wrench in the shaft turn the head, Remember it has a left handed threads on it so You will have to turn it to the right as You are looking at the bottom of the head. Hope this helps

The clamp on the shaft housing at the motor end is probably a little loose and has allowed the shaft to slip out enough to disengage the motor.

Question: Engine Seized

Shelly

I can't pull the line to start my trimmer. The repair shop said the engine seized up. What do I need to replace to fix it without buying a whole new machine?
Mark
Reply: Engine Seized

Mark

Hi Shelly,

I think the repair shop was right, it does sound like a seized engine. The engine seizes when it over heats. The overheating is typically cause by using fuel that either has no 2-cycle oil in it or not enough. It can also be caused by a carburetor that has been adjusted too lean. When the engine seizes basically the piston binds to the cylinder wall. Both of these items will need to be replaced. The two components make up a large portion of the engine.

To repair you will need the Cylinder Kit, which is part #530071581, the Piston Kit, which is part #530071999 and the Engine Gasket Kit, which is part #530069276.

I would suggest doing the tear down on the engine before ordering your parts. During the dis-assembly you may find it necessary to replace additional gaskets. Also you will want to closely inspect the crankshaft and the connecting rod bearing. Many times these parts will also be damaged in an overheated engine. If there is any scaring on the crankshaft or discoloration (bluing) of the metal you will also need to replace these items.

I hope this helps with your repair!

It is very rare that a 2 cycle engine should lock down, and only then when as Mark stated, it was ran without the 2 cycle oil. By the time you've invested in getting a new pison, ring set, and having the cyclinder head honed out, not to mention the time and headaches involved, you would have wished you'd bought a new one. Then there's the chance that it'll never run right again. Buy a new one and keep the old one for parts that you'll inevitably need for the new one.

Question: HELP

Ricky

How do hook up the fuel lines?
Patrick
Reply: HELP

Patrick

Hi there Ricky! On your fuel tank your going to have two lines. The feed line is going to have a fuel filter on the end of it, and the return line will not have anything on the end of it. The line with the fuel filter on the end of it is going to run to the inlet nipple on the bottom of the carburetor. On the top of the carburetor your going to have the outlet nipple. This hooks up to the suction side of the primer bulb.

If your not sure what side of the bulb is the suction side. It usually has one nipple that is centered on the backside and one that's off to the side a bit. The off center nipple is the suction side of the primer bulb. Any further doubt can be abolished simply but putting your finger over one of the nipples and giving it a push. If it sucks on your skin a little than that is the suction side.

After you hook up the suction side of the primer, the discharge nipple on the primer bulb gets hooked up to the return line on the gas tank.

Thanks Patrick for the help. Clear instructions ans easy to follow.
I love my WT3100 and have been at a great loss since it has be out of service.

This the worst product I have ever purchased. I brought the first at Sears and it was a problem from the start. I took it back to Sears and they advised they had been having problems and give me another one. It starting have the same problems as the first. It work good when is works. The drive and starter rope locks up. I would not recommend this WT3100 to anyone.
