I went to alcohol carburetor and trying to keep moisture and condensation to a minimum. They also say that you can pick up a little hp with one. I guess that I'll see about that.
Only thing I can think of is I switch to gas on the return road and get engine hot to burn off the moisture.
I run a toilet and I don’t have any moisture or condensation. After every pass I take the breathers out of the valve covers to let it breathe. Empty the puke tank.
