I didn't think that even a fully charged glow plug igniter could continuously run for 15 minutes....thanks for the tip, I'll try it the next time I fire it up. Before that, though, I'd like to find out what the shavings are......I don't wanna be running it if something's set up wrong. I'll probably take it to the LHS Saturday and take the shavings with me and see if they can tell me anything.
