Thanks for the advice guys. (I don't know if I'm "replying" right.) Shortly after writing that letter, the bike quit altogether. Since I just bought it from a 75yr. old guy on eBay, (3,800 orig. mi.) and the gas smelled a bit old, (and so did he) I cleaned out the carb. and tank. Still a no go. Looked for spark, and had none. Like an idiot, I completely overlooked the spark plug because it looked newish. A fresh plug and gas, and it runs well, but not perfect. I think it needs a carb and points tweek, and a good hard run.
I'm also having a '73 Yamaha RT360 (8900 orig mi.) delivered in a week or so I got on eBay, so I'm sure I'll need some more advice along the way.
Thanks again all....
