I'm doing the same as flyin shee in Feburary.my machine is jetted perfect for the summer.(60-80)I have a cut lid w\o the snarkel.Not 100% on how to set this thing up.I will remove the lid and have a timing plate to adjust.
I'm thinking 1/2 to 3/4 of a turn in on air screws,clip down one notch to richen.Confused about the main jet!!!!I would go two sizes up,but removing the air box lid could chage it more.???? 7 degree advanced with all race gas.What would be a good octane to run?
