This is my first post here or anywhere I am Eric, and I sure hope someone can help me. My 30hp will start up and idol (not the smoothest). But when I try to run it up past 4000rpm it will drop a cylinder, revving from 4000-5400 as the cylinder kicks in and out. I put it in the shop and they said it was a fuel problem and would have it fixed for under $100. Well after paying almost $500 for a $20 fuel pump, some rubber hoses, and a compression test. The motor runs no better, almost worse, they just upped the fuel to compensate for the problem. I have swapped the coils (cfm) , it will run on either one or both but only up to a certain rpm. Any help would be great!
