glow plugs

I keep thinking I'm going to over tighten the glow plugs and strip the threads in the engine head.Is there a way to torque them or do you just have to tighten by feel?These are os 2 stroke engines with the A 3 (#6) glow plugs.

Just snug it up good with a glo plu wrench or socket. It doesn't have to be super tight. The biggest problem I've seen is cross threaded glo plugs. Start it by hand. If you can't turn it with your fingers it is cross threaded.

Like WCB has said, there's no need to super-tighten it. If it's showing signs of leakage around the washer, it's probably because it's been removed a couple of times and the washer has been flattened or distorted. Don't try to remedy it by getting extra leverage on the glow plug wrench; just find another good washer.

The sealing washer is copper and you want to compress it slightly when you first install the plug. This way you can compress it more if you have to reinstall it later on...
