I bought the C-H ignition set-ups from C-H themselves. This included the hub with the timing magnet and the bracket to hold the pick up sensor, as well as the rear mounting plate. I bought the mufflers from them too.

The sensor mounting bracket is made in a mannor that it only fits the engine at the correct position. This means that there is no problem getting the timing set to the right advance.

I used 1/2" walbro (32) carbs like is on the Zenoah G-26 engine.

I run 18-8 props. The stock one turns 7400 rpm and the other has a cylinder modified by Mr Grant at C-H and it turns 7600 rpm.

They look as though they were model airplane engines from the beginning.

There was no cutting or sawing to the engine except the plastic back plate.

Enjoy,

Jim
