I recently purchased a hurricane 206 deck boat with a 1996 Yamaha C150TLRU outboard, carb model, it has 3 dual carbs on it.
I took the carbs off to clean them, i removed all the jets, blew compressed air though all the jet/pilot holes and passages, everything was clean and is clean.
only thing wrong that i found in the carbs was the float drop levels were totally random and off from the 16mm spec, so i set all the floats to 16mm without gasket per service manual.
The problem i am having is the motor only wants to reliably start and reliably idle when it is trimmed all the way down.
if i trim the motor up, not all the way up to the point the prop is out of the water, but a normal shallow water amount of trim, and idle in gear into a shallow dock, the motor will start shaking and stall within 20-30 seconds of being trimmed up.
if i give it gas and keep the rpms higher while trimmed up, say 1200+, it will keep running fine.
I cant wrap my mind around what can be causing the motor to idle perfect when trimmed all the way down, and stall in idle when trimmed up?
