I only have to pull my pull starter about 4 to 5 times to crank any of my 4-nitro vehicles. If you have your motor tuned right there should not be a problem with a Roto or pull starter and they should crank right up.

If you do not use ERA a arm mount for the MT 2 YOU WILL NOT BE ABLE TO HAVE A BUMPER! That is why it has what you call a round nose. Evidently you do not understand what I am trying to convey to you above. Do you or do you not understand what the difference between the MT1 and MT2 A arm mounts?
