MS880 spark plug

[spudulike]

My 660 does this same thing. Spits the spark plug out milling or long cuts. Plug is always tight and its done it from new.

 

No plug should do this as normal and the last few threads will be stripped out when it finally blows. New plugs can seem tight but the compression washer can compress and cause the plug to come loose.

 

I reckon that the first time it did it it took some of the thread with it and now there isn't enough to keep it in when hot.

I have bought a selection of the v coil kits, great satisfaction fixing stripped threads, how sad

Not at all, I hate stripped threads and missing bolts, always like fixing them:thumbup:

Ok we are both sad

If this repair all cocks up, I have some oversize options I have used in the past:001_rolleyes:
