Hey all
Have at least one misfiring cylinder in my 2010 Optimax 150 (edit: SN#1B787536). Have narrowed it down to cylinder(s) #5 (definite) and possibly also #3, both are on starboard side. Max RPM 4000 and rough idle. Noticed the problem at the lake, a few hours later in the day when running, it ran normally briefly before again losing power.
Have swapped out coil, plug, and wire on #5 with #1 (which I know to be firing) with no change. Plug in #5 was wet and smelled like gasoline when pulled. #5 side injector had enough gasoline built up behind it to pop out the injector when I pulled the allen screws - I don't know if this is normal but it didn't happen when I pulled the injectors for #1 or #3. All three injectors tested on my (very cheap) meter at 2.1ohm.
Where should I be looking next?
