micdanson88: I have the same model and it runs very rich to the point where it doesnt idle. I rebuilt the carb and it does the same thing?? any ideas?
Brian C. Iddon: Knowing where the caps are and how to just "pop" them off was very helpful for me! Thanks!! I have a Ryobi BC30 string trimmer.
Karen Nugent: try
yellownp22541: Thank you very much!, I was given the same exact model, which had been neglected. The reason why "It starts but won't stay on" now I know where to start once I replace the fuel tank which is cracked, the priming bulb is gone and it seems that the pull string will required replacement.
Make Way for the King!: Thanks! Mine was acting this way. I was sure it just needed cleaned. But after several attempts of cleaning the carb, the problem persisted. I then Googled my model and came across this video. Your problem was the same as mine. And your fix was also my fix. Thanks! I am embarrassed to admit it, but I was just getting ready to surrender and spend $50 on a brand new carb. Thanks for saving me $50.
anniversary4: thank you
anniversary4: great info as usual thanks I commented a week or so ago about working on one of these for a friend and got your response about the fuel line routing video. It was very helpful. Is there a sealant that can be used on the plastic gas tank. It is leaking at fuel line inlet that does not have the filter. Thank you
anniversary4: Thanks for this video don. Great as usual. A friend asked me to repair her Ryobi 410r tiller that is about 12 years old. It won't start and things are complicated by the fact that another friend worked on it and then admitted that he knows nothing about engines. He changed gas lines but I'm not sure about the routing. It does need a primer bulb and gas filter. Gas leaks from tank where lines enter/exit. Has compression and spark so that's good. Any hints on best place to get details regarding proper gas line routing and where filter belongs? . there are 2 lines into the tank, 2 on carb and of course 2 on primer. 2 lines on primer are 2 sizes. Thanks
Mark Vizer: I have same engine on string trimmer. Even after replacing fuel lines, primer bulb, air filter and cleaning carb, it only want to cold start with removing air cleaner and injecting starting fluid. It seems to flood very easily so when this happens, I have to remove spark lug, clean plug, pull though a few times and then start Once started, I runs well at high speed , tolerates load, and idles well. Any ideas?
Lakedog: Thanks Bud, worked like a charm on my Ryobi trimmer! saved me some money too! Much appreciated!
Mark Vizer: I adjusted hi speed screw and now it runs steadily. Only problem now is that it will only start if I prime with starter spray in carb. Not sure if primer bulb is working right. It is partially filled with gas, but doesn't fill up or feel firm.
Mark Vizer: Thanks, but above my skill level, unless there's a video on that, too. No chance that adjusting high speed screw would do the trick?
donyboy73: try a new carb kit
Mark Vizer: Same engine on a trimmer, froze entirely, now running again after gentle persuasion. Plan to adjust carb, because at full throttle it hunts up and down. Suggestions?
troyoverton14: Sir: Please accept my most sincere thanks for this video. My same tiller was not running and I used your video and tuned it right up, now she runs like a champ!
donyboy73: try a new carb kit
Looey Tremblay: dony boy if i pour gas in my carb it runs perfectly, but the fricking thing wont start, new gas lines and bulb and gas circulates through them and i cleaned carb
76chyanne: i have a bolens like this why is it spiting fuel out the top of fuel cap any idea what would cause that
xplor nevada: Thanks! My Bolens bl410 cultivator is almost the same & had the same problem. My Walbro carb screws aren't slotted, so I tapped the high screw with a smal., sharp screwdriver and a little hammer to turn it an eighth of a turn.
Saved me a trip to the shop!
donyboy73: @76chyanne sounds like the air filter may be plugged, time for a new one
