Status: offline 		running lean is the main thing that kills glow plugs. this can also happen if you have a leak somewhere. ive once seen an axial engine that had a leak which caused it to burn 3 glow plugs in just a couple of tanks. it was like a glow plug every 2 - 4 tanks. This happened no matter how it was tuned, and it was all because of the air leak.

leaks suck,start with the simple stuff.head bolts,fuel lines,

Status: offline 		this may be off topic but what size is the 427? is it a .26 or a .28?
