What would cause the Vegas .18 to pop glow plugs after each run?
Runs great on 30% with 20% oil ran all day Sunday fine A buddy runs the same fuel
same plug for 3 days today mine pop a plug after each run 6 in all ANY HELP would be great

Richen the carb. It's probably frying sooner but the coil is staying hot enough to keep it running until you shut it down.
How are they looking? Is the coil mangled, shiny or gone?

In addition to what Ron said, what plugs are you running? When running 30% nitro you should be running a plug toward the cool range.

Well any richer than my 2 1/2 turns out on HSN is way to rich it want run want get on top of the water 2 1/2 to 2 1/4 seem to the best
but it just eats plugs. And they are OS A5 and tried a mc 9 but same

just richen out very slightly and try it. depending on atmosperic pressure or sea level these engines are pretty sensitive.

We are having the best luck with 30% N and 20%oil using o.s. #8
