RE: Spark plug kit to convert a glow engine?
In parts of the world where glow fuel is not to be had, manyfolks run 4c engines on gas. About 15% oil and ignition, lots of diddling with the stock carb to get things right.
On the 120 and up there is a 4c Walbro that will work if you make a new intake to mount it.
It can be done just takes TIME, TALENT and MONEY
