choke handle
Question by spencer

My wife backed over my trimmer and it appears that the only thing really broken is the choke handle, the one you move between A to C positions. Can this be yellow handle be replaced or is it part of the carburetor and you have to replace the whole carb unit?

Respond to this question

Posted By Mark

Hi Spencer,

Unfortunately the choke lever is only sold as part of the carburetor assembly. The carburetor is part #308054003 and is available from http://ereplacementparts.com.

I hope this helps with your repair!

Won
Question by Larry

The only way to start my unit is to spray starter fluid in.Once I let up on throttle, engine stops. I think it needs a carburetor rebuild kit. Is there one available? Could it be anything else? New gas, new plug installed.

Respond to this question

Response #1
Posted By Mark

Hi Larry,

It sounds like a clogged carburetor to me as well. There is no carb kit available for this trimmer. You will need to simply replace the carb. It is also a good idea to replace the air filter at the same time. The carburetor is part #308054003 and the air filter is part #98760. Both are available from http://ereplacementparts.com.

Good luck with your repair!

Ryobi BC30 dead
Question by Richard

Have had this trimmer for almost two years. Used it not continuously. The other day while working with the edger adapter suddenly it stop and went dead. Changed spark plug but noticed no spark coming when pulling the rope. Any suggestions please? Thanks.

Respond to this question

Response #1
Posted By Mark

Hi Richard,

No spark is usually an indication of a bad ignition coil. I would first check for spark with a spark tester. If the spark tester confirms that spark is not present then the coil will be the problem. The ignition coil is part #850080001 and is available from http://ereplacementparts.com.

I hope this helps with your repair!

hard to start
Question by pauric

ryobi brushcutter very hard to start

Respond to this question

Response #1
Posted By Mark

Hi Pauric,

If the trimmer is hard to start but then runs OK once started I would consider doing a tune up. To do a basic tune up you will need to replace the air filter, the fuel filter and the spark plug. It is a good idea to do a basic tuneup at the beginning of each season.
For your trimmer you will need the following parts...

Air filter - #98760
Spark Plug - #870174001
Fuel filter - #530091878

Ryobi only offers the fuel filter as part of the gas tank assembly. The fuel filter listed is from Poulan. In tank fuel filters are pretty universal and the one from Poulan should work just fine.

If the engine still doesn't start easily and run well after the tune up then it likely has a clogged carburetor. the carburetor will need to be replaced. The carburetor can become plugged with dirt and other debris. If gas is left in the tool for more than a couple of months it will breakdown and turn to a varnish in the carburetor. This will also plug the carburetor. The carburetor is part #308054013.

All of these parts are available from http://ereplacementparts.com.

Good luck with your repair!

rotor
Question by lmm

how do you line up rotor for correct timing

Respond to this question

Response #1
Posted By Mark

Hello,

The new rotor has a key cast into it that should line up to a key way on the motor. With the key and key way aligned the rotor will be in the proper orientation for proper timing.

I hope this helps with your repair!

clamp to link the two parts of trimmer
Question by loc

I have a Ryobi trimmer that can be used to adapt an edger but the clamp that links the edger and the shaft is so weak that when starting the engine the edger part is disconnected due to vibration

Respond to this question

Response #1
Posted By Mark

Hi Loc,

I think you could solve the problem but it would take a bit of modification.

The end of the bolt opposite which the knob is attached to has been mushroomed so that it can't come loose and be lost. You will need to grind the mushroomed part off so that the bolt can be removed. Take the bolt to a home center with you. Find a flat washer and a rubber washer that will fit the bolt. Slide the rubber washer on the bolt first followed by the flat washer. Now reinstall the bolt onto the trimmer. The rubber washer should provide enough cushion and grip to keep the knob from coming loose.

I hope this helps!

Fuel filter
Question by HC

Can not seem to locate fuel filter in the parts diagram. Do I have to replace the whole fuel tank? This is model RY30004.

Respond to this question

Response #1
Posted By j.seveer@yahoo.com

Fuel line and filter can be purchased at any LM repair shop. bring your tank with you. Buy about 2 feet of fuel line. remove old line. CUT ONE END OF NEW LINE on a bevel (point) Force it through the hole in the tank closest to the filler cap with a twisting motion (clockwise) until the end comes out the filler cap enough that you can trim the bevel off and put the filter on. Pull the line back through till filter is laying flat on it's side in bottom of tank. Trim to length and attach to carb. Treat other line likewise..A little oil on line helps to get thru hole in tank Filter 3.00 line 2.00 per foot

rope wont pull
Question by deanerboy

can't pull rope 0nbc30-ry30004A. how do I repair?

Respond to this question

Response #1
Posted By Jeff

The rope on mine jumped off the starter pulley assembly and got looped around the tabs on the baffle (part 41 above). I had to take it all apart to get the rope re-wound. Just be careful of the rope return spring and container! The above diagrams are very helpful. To get the Drum and Connector (part 33 above) off, you need a T20 screwdriver, about 3 in long and something to keep the piston/rotor from turning.

Do the clutches screw on or slide on?

Drum Connector

Review by jim

My Ryobi bc30 lasted one season and then had major carburetor problems couldn't keep it running fresh gas didn't even help I also was suprised to find it was a homelite trimmer I will never buy another ryobi. For the cost of the repair I can almost buy a newer model. very very disapointed.

Respond to this review

Review by John

Very surprised to learn it's really a Homelite, a brand I have been very disappointed with over the years and would never have purchased. It ran well for 1 season then began losing power due to carbuerator problems. The replacement carbuerator costs nearly as much as the entire machine! I'm buying a Stihl.

Review by Scott

Nothing but problems. Gas cap leaks, fuel line appears not to be fuel resistant-rots in 2 years, parts too expensive, vibrates too much- makes hands go numb, constant carb problems, wont reach full speed
