Eating through glow plugs today? A costly day.. Why?
Hey Guys,
I spent the day at the track today with a friend. we were running 3 buggies and went through 6 glow pulgs. What is the casue for a glow plug to burn out so quick. At $5 a piece that sucks.
I was running odonnell's purple which is a meduim temp plug in a hyper .21 motor and a picco .27. Running Odonnell 30% race.
The motor temps were in the 200 to 240 range. Smooth power in the power range.
What would be casuing this? lean? temps were good?
What should the head clearance be when running 30% fuel? I want to make sure the heads are shimmed right before something goes worng..
Sorry for all the questions... Thank again for the help.
