Mad Jack, Tell me if i am wrong What you mean is with the engine config your trying at the moment 6.5mm carb restrictor and 9901 pipe and so on the engine has plenty of power but more importly its useable power and also important more fuel econamy over the older novarossi engines?. On avarge with that config what run times are you guys getting from a buggy 125cc fuel tank?. Regards Jeremy.

nope, I would buy another 367

for me, after figuring in the cost of the extras the overall price is close to the 21-7

This is the latest evolution / design from Nova, using the new case, front bearing, back plate, crank etc...

in the past I have run 7mm or 7.5mm venturi's in my other motors and would have never thought of running a 6.5mm and having enough power (this motor has less than 2 gallons thru it). I'm sure at some point I'll throw in a 7.5mm to see what is does to run time and power :sweat:

about 8:30mins. in the buggy, but it is still pretty tight. (guess it will finish close to 9min+...I hope ;) )
