Schizo Posted December 29, 2003 Report Share Posted December 29, 2003 I'm sure you will have to run atleast a 50/50 mix of race gas. Do a compression check. You should be able to run pump gas anything below about 160 psi but I'll bet you are above that. Quote Link to comment Share on other sites More sharing options...

dlnoss Posted December 30, 2003 Report Share Posted December 30, 2003 That's pretty small. What's your elevation? Has anything else been done to the engine? Quote Link to comment Share on other sites More sharing options...
