Thanks, haven’t seen one of those neon testers before and I’ll pick one up. I’ll take the recoil off tonight and have a look, I’m curious if the “tune-up” or any “tune-up” ever replaced the coils. We ran about 30 gallons of gas thru the motor in 3 weeks of vacation, so it was working pretty darn well… until half-way thru the last batch of different gas mix (see original post)… wasn’t sure if it was coincidence or not.

Fuel pump is in the top bypass, intake looks like it hasn’t been removed in decades. I suspect the recent tune-up was a carb clean, plugs, some rickety fuel pump change and lower unit gear oil.

I did order a few J8C plugs to try? Also wondering if I should try decarbing the engine. Going back to the lake in two weeks and trying to button up any issues so we can fish the heck out of this boat again.
