My chrysler 20hp outboard starts in one pull and runs excellent at idle. Plenty of blue smoke. When I give it full throttle, it does not accelerate at first. It sputters/jumps like it wants to accelerate but it doesn't. It sometimes takes 5-10 minutes before you can get it to go. Once you get it to run wide open It will run all day as long as you never let of the throttle. Once you let it back to idle, you restart the process. I have cleaned the carburetor twice and am 99% sure the carb is clear. It has good spark, good compression, fresh properly mixed gas, points set correctly, throttle roller set properly on stator plate, etc.
The only thing I have not replaced is the fuel pump diaphragm. It still has the original 1971 fuel pump but squeezing the primer bulb at any speed does nothing. I am stumped and stressed about this outboard. Driving me crazy!
Thanks for any help.
