i've got the same motor exept its a 6.5, some guys from the kart forum told me to add 18lb valve springs advance the timing to 6 degrees, and get a bigger carb like u said.
got this frame and motor from acme motor in detroit, needs pretty much everything including a sand blast job, but will clean up real nice. i plan to mildly mod the engine and go with the torque converter, nuthing is bolted right now just mocked up, stay tuned for more pics throughout the build...
i kinda wanna trade it for a smaller engine to fit my bike. so if anyone around here has a modded clone or nice tecumseh 6hp+ flathead let me know. if not i will see what i can do with it, but reality is starting to set in lol and i dont have the patience
just picked it up the other nite, besides the governor, what mods can i do to beef it up, i am not looking for a major gain maybe just 2.5hp. o yea, will any 390 parts fit this?? i need all info, thanks guys
