When someone brings in a ryobi or the like I used to replace fuel lines if that was all it needed. Not any more. I don't work on them at all anymore.
Let me point out the main reasons I don’t work on Ryobi (or any other off brand handheld equipment any longer):
1). The juice is not worth the squeeze. Too much labor time for low profit return.
2). Mixed success. Not uncommon to spend a lot of time trying to get it run, only to have it run poorly or intermittent hard starts.
3). No compression. Scored piston, rings, and cylinder. Notify customer and they never come back to pay for diagnostic charge.
4). Repair often costs too much in relation to initial cost. Remember the 50% of retail vs repair cost ratio general rule of thumb.
5). The warranty is only as good as a local shop willing to do the work, or repair after the warranty. Let’s face it, the customer cheaped out and bought a crappy product and now wants a shop to polish a turd.
6). I don’t enjoy working on cheap, crappy equipment. Old equipment is better than cheap crappy handheld equipment.
