Default Using 4 Glow plugs in two hours??? gg :eek:

Hey guys just got my friends nitro car going and the motor (gx21 kyosho) is using lots of glow plugs :/ the motor was just rebuilt at the hobby shop with a new piston and sleeve. The tune is good but yet it just goes through glow plugs like crazy, any ideas?

Or bad rear bearing?? Conrod wear can also cause the engine to eat glow plugs. I'd tell him to stop running the engine, strip it an inspect for wear. Continued use is not a good idea!

I say buy a new motor...

If you have the cash.

Like the others say it could be

head shims
wrong plug
bad rear bearing
Conrod wear

Which will cost you more vs buying new sir.

Something to think about.

Are you sure it's not to lean ? That's the most common reason to burn them out.
