9.9 Chugs intermittently

• Hi all, I found this archived thread from poster named “ itsbeal”. It was dated April of 2006 and he describes my exact problem.

• 92 Honda 4 stroke coil???

I have a 92 Honda 9.9 four stroke.(serial# BABL-1200694; model# BF9.9AM) About a year and a half ago, the coil went bad (or so it seemed) and I had it replaced. It seemed that the secondary windings in the coil went bad according to my mechanic. Here it is a year & a half later, and the blasted thing is doing the exact same thing as before. When running, it chugs real bad at times (but runs smoothly the rest of the time). It acts like its only hitting on one cylinder. I should also say that this is an intermittent problem.

Like him I have spent over $300 at a Honda dealership (new fuel line, filter, carb cleaning, tune up etc.) with no results. I have not yet replaced any coils, but I have checked and cleaned all electrical connections

A “weluvlife” responded saying to pull and put back one leg of the coil wire. I have tried this with very limited success

The last thing mentioned was to disconnect the wires to the oil pressure safety switch. Again this has not helped
So my question is does anyone know where I should look next
