A fresh of eyes could actually help you Billy. If you have egt and/or o2 numbers for the entire pulls, we could put that issue to rest right quick. David is "the man" for running alcohol and Ron's stuff and will help you if you let him. I know you are certain that it's not a fuel system issue, but an opinion from someone who knows his stuff and doesn't have a dog in this fight might be a good idea......
