Running so rich, that the boat is smoking at idle. My transom is black. This just started this year. (had a pile of young kids with me, so didn't want to pop open the cowl and start digging around, but) when I got home i made sure there was nothing plugging the spark arrestor..
What now? carb rebuild time?

Re: Running very rich...

Had her out a few more times...Choke is opening fully, boat is up to operating temp. Seems to happen intermittently. New plugs. I'm stumped. I'm an EFI kinda guy...
