Sounds like fuel. But that's stating with no other evidence.

First thing I'd do is run a colder plug. Depending on the temperature outside, it might just be toooo hot. If a plug is burning up, it's gonna crack, then break completely.

Try a colder plug, also, name off some of the things it's doing.

Is it running hot?
Hard to start?
What fuel?
Clean air filter?

Also, try clean the motor fully. Run some after run oil through it. Sometimes dirt can get in there and cause problems like that. If so, GET IT OUT. Dirt can kill your engine quicker then anything. 🙂

Buring glow plus out in a matter of min .. Sounds to me like you have METAL in your engine .. pull the head off and look at top of piston .. LMK what you find

Lean. If its burning them up half way up the coil, overheating is the only thing I can see. Theres probably metal in it now.

Could it be the ignitor itself maybe getting them too hot?

 

[Grumpy1822]

Na, I don't think you could have enough juice to get an ignightor that hot.
