RE: cox 140 gas engine
Hey Otter..
I have one of those which I converted to CDI. I have a pic posted in the New CDI forum. I had no luck with the grey plastic carb that it came with so I bolted on a Walbro carb to run it.. Seems to work great for me. The first one I had, I bolted onto a Bud Nosen Citabria and it flew so realistic I was impressed.
