forrest411 Posted October 8, 2010 Author Report Posted October 8, 2010 93 mixed 40:1 Someone told me that I could run 19cc domes on pump gas. Is anyone running a similar setup like this? Quote

firebanshee Posted October 9, 2010 Report Posted October 9, 2010 What is your elevation? At sea level and +4 on the timing to be safe you should run 21cc domes on pump gas.imo Quote
forrest411 Posted October 9, 2010 Author Report Posted October 9, 2010 What is your elevation? At sea level and +4 on the timing to be safe you should run 21cc domes on pump gas.imo I'm in the midwest about 2 hours northwest of the Badlands in Attica, IN. Some of the Gas City stations by me use to sell 110 Racing gas. Now the still sell what they call racing gas, but it is only 100 octane. When I put the motor back together I had the head shaved .04, but I just got this pro-design cool head, but I don't know if it will be worth the hassle or not. How much of a difference do these really make? I don't really have a problem with it running to hot as it is. This site has been a great source of help to me in the rebuilding process. Just started to work on another one for my sons. Thanks for the help! Quote
