2000 Johnson J50PLSSM
i can get the engine to start by manually opening throttle butterflies or advancing the throttle in neutral. But she smokes like mad and there’s unburnt fuel coming out of the exhaust. If I bring throttle down to idle she dies. Here’s what I’ve done so far:
compression 120 on both
verified spark jumps 7/16 gap on both cyls
verified WOT timing using joe reeves method
rebuilt both carbs (done these style of carbs many times. They were in very good condition when I pulled apart)
new spark plugs
cleaned grounds
hooked to external tank for testing
its as if she’s flooding out.
Advice appreciated.
