Jspeed,
Not to worry, my Sportwerks engine is bone-stock on the inside. I have had neither the cooling head or the pullstart assembly off of the engine. Thanks for the response about the engine. Got an Axial one off your list (had it for months, just too lazy to change it out) for my IGT2. But, I may dip and get a higher powered engine to run the IGT2 in the open class if I can make this race.
