Hi all
I just bought a speedboat with a 115 V4 yam, it starts and runs perfectly but when I open up from idle it runs real rough and almost stalls for a second or two and then takes off like a rocket and runs perfectly. Im using quicksilver outboard 2 stroke oil but heres the thing - I never fully trust an oil pump until I test it so at the moment I am running on the oil pump and a 50:1 premix in the tank (only until I can establish that the level in the reservoir is dropping and all is operating well). Could this be the cause of my dead spot - too rich fuel? I am going to change the plugs also. I removed the plugs on the day but they wernt excessively gooed up also she is not excessively smokey when running but there is a goood bit of smoke at start up. Also she accelerated perfectly without any hesitation on the warm up lever although she is obviously not under load then. by the way I checked compression and its good and even on all cyls.
Any ideas?
Please dont mention a carb rebuilt as I dont want to(I am pretty handy and am well tooled up but I never have before) and the local dealers are almost worse than useless.
Another question doens the oil level alarm work off the under hood tank or the inboard tank on these models?
