all of a sudden my 1990 150 can only get to about 3500rpms and appears to be down at least one cylinder. i do get the occasional "full power" surge. when at idle i can pull the wires to the bottom cyl in each bank and it doesnt change rpms at all so it seems they might be the culprit.
it has spark to all cylinders and perfect compression. i pulled the carbs and am in the process of cleaning them but i dont think thats it since theyre reasonably clean. and i can see the reeds and they're perfect.
what else can it be. it *seems the other 4 cylinders are running perfect. any ideas?
