wet spark plug?

[FlexBusterman]

I'm a french boy but i'll try to explain my trouble. I rebuilt my banshee motor with a new crank, piston, port cylindres, boysen reed valve, boots bottle and timing key. i dont no why, but my spark plug are always wet. I have jetting my carb in 5 different way but it's always the same problem. It WAS THE SAME WITH A 220 MAIN OR A 310 MAIN WITH A LOWER POSITION NEEDLE. MY SPARK PLUG ARE ALWAYS WET BUT MY MOTOR RUN GOOD FOR A FEW MINUTES. THATS WY I THINK IT'S NOT MY TIMING??

find someone with a similar set up as you and set your jetting up like theirs.

that sounds about right. does your coolant level get low. and ditch the boost bottle.

 

just do a search about it if you want to know why B.R.A.B.B.

what do you mean by wet? take a pic of your plugs and post it. it could be oil, coolant if you have a bad head gasket.
