Regarding the G-62. Just contact Ralph at RCIGN to get the best deal on the motor. Whilr you're at it, get his lightened version with the electronic ignition. Talk to him about mounts and mufflers. The stock 62 muffler is crap. Abell and JA engineering make some good ones for the engine.

The 62 choke can be difficult to work with until you add and additional bellcrank to the side of the motor. Then things start getting a lot easioer. Again, talk to Ralph. There is NO other better authority on that engine.
