Thread: how to clean spark plugs?

Tweet

well guys. Torch worked. had to do it 3 times. after I did it the first time, It did fire but it ran very weak, and only ran for a minuite. the second time, it sounded ok, I put it in gear, got it going, and a few feet from where it started, it died. the third time, I really made shure it was as clean as I could get it. got it started, was running ok, so I put it in gear, and took off. spark was very weak at first, almost couldn't keep it running, but I kept it at a throttle position that it would stay running, and eventually, I was able to wind it up and put it in second, and altho it wasn't running the best at that point, I just kept with it, and the spark plug cleaned itself off. I bought a new plug, NGK-BR8- ES today, went to pull the cap off the top that is supposto screw on ( my bike cannot use plugs with them on, plug wire won't fit it ) and ended up pulling the center shaft out of it, took a good look at this 1, and it has a non removable cap. only $2.00 with tax.

what kind of bike you have, i know NGK makes capless plugs for both my yamaha's.... btw a good way to clean a plug when its fouled on a dirtbike, is blast it with some carb cleaner and while its still soaked, light here up.... can be a little dangerous, but it does a hell of a job.... trick has saved me once or twice out in the middle of the desert..... luckily i keep a can in my backpack with my other couple tools i keep....btw generally if everything is mechanically sound on a two stroke bike, the reason the plugs get fouled is from choking it for too long....other than that your carb might need a rebuild or you're mixing too much oil into your fuel.....

the bike is a '78 Suzuki DS 100. the plug I bought for it b4, I just unscrewed the cap. yeah, I ran the oil mix a little rich this last time round, that's what fouled it, I'm shure. good idea with the carb cleaner, never thought of that.

ok... i dont know my older suzukis too well.... but yeah, that carb cleaner trick works like a charm
