RE: Converting a 60 glow to gas (with glow plug)
The better way around is sticking to glow fuel, and fit an Rcexl ignition + 1/4"x32 spark plug. Learn how to adjust the needles. One click sometimes is plenty.
So far, all who converted to spark ignition with glow fuel were raving about it. Ease of starting, lower reliable idle, smoother running, lower fuel consumption.
