well use say to go with a 39cc though i wouldent know what parts to get or it cab reeds clutch crank.... and besides i can only buy parts from ebay

and basicly the only thing i can get there is reeds and a cab 4 it....
and yess i am aware that smaller cc motors revv higher
gas nitro cars rev to 40,000rmp
soo i think ima get the 45cc head kit, 19mm dellorto carbie,fiber glass reeds, and also exhaust heat wrap to stop oil leaking every where and wont look to bad i think ima stick with the clutch dont wanna buy a new 1 as it will cost more than everything i just bought
only got another $20 to spend:P
