I always run 93 non-ethanol. BuggyMaster said his was showing optimal burn and plug reading at around 15:1. I'm kind of torn where to go as I don't really have much area to do WOT tests and compare the plug reading to the AFR from my wideband.
Jman I was pretty sure the pipe was stainless. I haven't had any time to even get the bung welded so who knows when I will get this completed on either buggy and the new 150 engine broken in.
