David:
I have a Yanmar 2GMF.....where the throttle cable meets the engine,
there is an screw/bolt that can be easily adjusted to set the 'minimum
idle speed'......I have mine set about 800 RPM's so I can not adjust the
throttle to run the engine below 800 RPM's.
I don't have the same issue as you with the engine stalling when you
shift into reverse. However, I do not think increasing the minimum idle
speed much above 1000 RPM's is the solutionto your problem. I am no
marine engine mechanic but I think you should be able to shift into
reverse at 1000 RPM's without stalling.
I would address this before adjusting the idle RPM's higher than
1000.....can't be good on the transmission when you shift into gear(s)
at a higher RPM than 1000.

All this discussion of engine (Universal M4-30) starting has reminded
me of something I want to do in the spring, but am not sure how to
approach. My engine runs fine at idle, which is around 1000rpm (don’t
remember exactly what gauge reads). If I shift into reverse it almost
always stalls. If I advance the throttle slightly, it does not stall.
This is obviously a real problem when docking as I can’t count on
slowing down when I need to without restarting the engine. So the
question is: what is how to advance the idle speed slightly? I can
imagine doing this at the Edson lever end or the engine end and not
sure which is the right or best way to do it. Thanks- Dave
