Finally solved the carb problems on my RCGF 20cc and am now running it on Gas/Glow and am totally pleased.

Had to swap out the Chinese carb for a Walbro I had in the spares box. I think it came off of a leaf blower. Already had a alky resistant diaphram in it and all I had to do was some rear plumbing work to get the pulse line working for the fuel pump. I'm using the 1/3rd ST 10/10 glow fuel and 2/3rds gasoline mix. I plan on mixing just a gallon at a time to assure it's fresh.

The engine transitions good, and idles at a tickover. Starting is easy as the new carb has a primer bulb built in to get the carb wet.

Removing the ignition module and battery really made a big difference in the front of the fuselage. Lots of room now.

Thanks all for you're help.

And thanks fujiman for milling the glow plug adapter. Works like a charm.

I'm thinking my next project will be to modify one of the weed eater engines I have on hand and convert it to Gas/Glow. Not having to worry about the ignition should make it much easier.
