I run mine on small tracks with S&W fuel and a picco carb with a 6mm insert and I make 10 minute pit stops. I will admit it's probably the worst fuel milage of all my engines, clocked or stock but I don't care. I love it and someone told me one less crash every race makes up for the one more pit stop so it's really not that big a deal. Ryan Maifeld pits more with his reedy's but it's not hurting his results much
