Bought a used 97 Johnson J8REUC to replace my old Suzuki 8hp. Runs great but gets far worse fuel milage than the Suzuki and all other friend's outboards with similar sized 2-stroke outboards.
-It's on an 11' inflatable that weighs about 100lbs.
-Starts, idles, and runs great up top but while just putting around just off idle it smells very rich and goes through way too much gas.
-Sea-level running in So Cal
-Good compression
-Champion QL77JC4, although I'm going to try to run a hotter plug and lean out the low speed needle this week.
-Low speed needle likes about 2.5-3 turns out. Idles too low and misses if leaner. Turning up the idle to compensate for a leaner setting really kills the milage even more.
-50 main jet
-As soon as I'm off idle I can see what seems like too much fuel coming out of the float bowl as I look down the carb throat.
-I rebuilt the carb and find no issues.
I have a good understanding of 2-strokes and have been racing MC with them for years.
Any sugestions?
