I read about this long ago it was being tested in the 90's ,,does anyone still make a conversion kit to run a .40 size engine on spark with gas and oil???.....yes it was made, I think around 94 there was a review in RCM on it...Rog

Easy enough to do, but more trouble than it's worth, costs abot $150....
The carb gets really touchy....Just as messy as a glow engine, you use the same amount of oil in the fuel...

The four stroke glow engines adapt real well to ignition but to still use glow fuel. They are really nice running. The ones I've been around were in the 90 and 120 size. It still cost $150.

Enjoy,

A .40 is sorta small for conversion, unless you have a special need.
