I am fairly certain with the advanced timing you are supposed to run higher octane fuel. Quote Link to comment Share on other sites More sharing options...
quick-z Posted April 23, 2005 Author Report Share Posted April 23, 2005 I was running super unleaed pump gas.If I should be running race fuel please let me know. And thats what I will start running when I get it all back together thanks Quote Link to comment Share on other sites More sharing options...
sredish Posted April 24, 2005 Report Share Posted April 24, 2005 With 22cc domes, I don't see a need for race gas. That jetting doesn't sound way off. Those pipes don't flow like Fatties or Toomeys. 270s or 280s would be pretty close. I'd probably say try some 280s. Run a plug check afterwards to verify the jetting.
