Re: Full throttle needed to start Yanmar 2GM20F
I think OB and Minne are on the right track.. while 350 compression may be on the low side I don't think it's low enough to make starting problematic with good fuel delivery. And that means timing and proper atomization.
If you're cranking for excessive time periods try to remember to leave your RW intake closed until the engine catches. Flooding the exhaust system with RWC is never a good thing.
Having to use wide open throttle during starting seems to be SOP for some of these older Yanmars..
Ok, I am listening, does this apply to fresh water culled engines?
