Hello,
We have bought a slightly used BF15D last year, we use it for 14 days every year. The first year everything was smooth until the very last day where the engine couldn't keep running at low rpm and stalled. Was hard to start. In order to clean the carbs, I used some injector cleaner in fuel and tried choke at full throttle to create vacuum at intake to suck debries out of the nozzles. This seemed to help a little but didn't have a chance to observe it too long.
This year we ran the engine on the last year fuel mixture (with the cleaner) and it run quite well but there were still some misfires at low rpms. We refilled fresh gasoline and used the cleaner again and the things retured to the bad side. Once again the engine is hard to start and stalls from low rpm, but idles and revs at high rpm just fine!
I tried to keep the prime bulb upwards but I noticed that it drains the gasoline back to tank when the engine is not running and is quite empty when it is running. But it is possible to reach hard state when pumping manually. Even with manual pressure it does not affect the engine run though. I guess it is good idea to replace the hose with bulb, but it will not solve the issue with misfires/stall at low rpms as it is not affected by manual pressure.
Any ideas guys? Thank you!
