Update, in case anyone is interested. I got the conversion parts and have installed pretty much everything. The carb mount is a bit tall, but hopefully will work out ok. I am using an ignition board that Ralph @ RCignitions was kind enough to blue light for me. The coil and metal bits and pieces came from CH. I have the engine timed and am ready to run it..................except! The metal parts I got from CH didn't include the prop bolt. I used one from my G-38 to set the timing, but I don't think it is really an exact fit. The nice folks at CH are supposed to send out the bolt and prop washer tomorrow. I'll attempt to crank her up when the right parts get here. About a week, judging from the original order.
