Do you have an LHS you can take it to?
Also, are you running 2 speed?
Like I was saying, I wasn't certain whether or not it would be right. I just was pointing out that when I bought one I had to make the choice whether or not I wanted the side/rear exhaust, bump/pull start, single/2 speed. All for the reasons of how things layout and FIT on the chassis.
So with all those combinations you can see why I wouldnt be certain.......
kwong has probably already done it.
I started with an NTC3 rear exhaust, 2 speed, pull start right from the get go. So I'm not the expert on making the RTR work that way.
