This is what rattles my brain. I experienced this on Saturday, when finishing breaking in my mag .28 . If it glows why in the world won't it ignite the methane ?
Ill try this pull the coil thing with an very used and abused OS 8 plug I have.
First of all, you don't run your engine on methane... methane is a gas... you could produce fairly large quantities of it by eating a lot of beans...
A plug can be ruined even though it looks ok and still glows. I suspect it has something to do with the coating of the plug wire that acts as a catalist in the methanol-oxygen reaction. If this coating is "damaged" one way or another, your plug is basically ruined. Kinda like running leaded gas in a car that has a catalyct converter... you would be shopping for a new cat very fast.
On the other hand, a plug may look completey wasted, and still function fine. Straightening the wire on such a plug is probably fine. But be careful while you're at it, like WR said.
