have a 91 pro v 150.... runs fine when I’m on it 1/2 to full throttle.... problem is when I get back down to idle speed in gear she dies. Carbs just cleaned... same thing starting.... it’ll start let it warm up put it in gear and dies.... haven’t synced carbs or air/fuel...

do yall have any ideas you care to share?

Also if you have any pictures that would show exactly where to adjust air fuel as well as idle I’d appreciate it

Seems that idle rpm is set too low when throttling back from wot speed. There should be a master screw that adjust all carbs in a row ? If carbs are well synched at idle speed just need a slight CW screw adjustment to pull idle revs slight up for OB not to die.

I would suggest going thru the carbs. idle circuit could be plugged on more than one carb.
