going thru plugs

[b-rian]

i seem to be going through plugs like candy.i bought anew 2.5R. Broke it in proper.if i shut it off by blocking the exhaust it will kill the plug.I tried to extend my fuel supply line so i could pinch it with the body on, but then it was next to impossible to start.the temp outside is about 45F.I'm running 20% fuel and I've tried a few different plug types.seems to run ok,but when it warms up the low end seems sluggish.someone please help so i dont spend my paycheck on glow plugs

It's either lean, or it has an air leak causing a lean condition. What's the temps? The almost impossible to start leads me to believe the fuel system is having a hard time building pressure and/or it's getting hot. Check the tank cap, header, coupler and fuel lines first. If you didn't seal the engine before installing it, I highly recommend it. Read the Tuning Tips and Tricks sticky at the top of the nitro forum for details on sealing a nitro engine.

Sounds lean to me if its eating plugs...

Try an OS LC3 hot plug..

Should solve the problems along with richening it up...
