I just started using that stuff and noticed that it doesnt huff anymore either. If it blows the motor it just gives me a reason to do a PI swapMine used to do that, too. I add a pint of Motor Honey every once in awhile and mine doesn't do it anymore. Some might argue that is not that great for these motors with their overhead cams and no cam bearings, but I've been doing it for years and I am FAR from easy on my 'Bird.
okay guys, what the heck is a "PI swap"?
