does not unscrew. They don't all do that. They used to, not anymore. I've been through the spark plug boxes on the shelf at the parts store and its not there...
I bet you're having the same problem I ran into. Our (mine, yours, ERCs ect) vintage bikes are very old and a bit rare and there really isn't a listing for the correct plug anywhere except for in the owners manual. Which until the joys of the internet weren't readily available until recent years I'm guessing. My point is, when you're trying to get a plug to work on something this old but have nothing to go off of, you literally will try anything that works. Which for our old vintage bikes, happens to be a tractor plug that does NOT have the threaded nipple. I'm willing to bet that being our bikes are the same era, they take the same plug. Try NGK part # B6HS. I called NGK personally to sort this out and this is the plug the crosses over from the vintage Champion plug listed in my repair manual.Scottie
I've checked the filter recently and tapped it out. It was perfectly dry with little to no particles.Yep, the bike has an 02 sensor. I'll see if I can determine if there's a leak, I remember seeing somewhere that you can spray some sort of cleaning product around that join between the pipe and engine to make it easier to spot a leak- is this something that you guys have heard of?the guy I bought the bike off 'advised' me to use the choke and hold it down whist the engine warmed up...maybe that contributed to the carbon?
