OS TZ/TM .18 crankshafts
 

I've been told that, with the exception of the pull-start nub and pilot/shaft variations, the timing is essentially identical. Is this true? :confused:

I've looked at them and they look exactly the same. this is by eyeball. I think the only difference is for the T-maxx/Revo clutch nut and the pull start nub. other then that they look identical. The crank cases look identical too.
