One of the guys I run with recommended that mixture. He’s been racing for a long time, and really fast on the track. Usually either first or second in his class. I tend to listen to what he says. I always forget to ask him about the no smoke issue I have, and when I see him next I’ll be sure to bring it up.
But with the heavier oil mix, it seems like I should be seeing more smoke than I do. I’ll get access to my notes and carb tomorrow and report back what I find out.
