Thanks it does seem like the throttle cable is getting bound up somewhere, it's kinda moot now though. I killed the old girl last Tuesday.
I was going flat out and felt a hiccup and bang and she quit. Didn't freeze up but no go, not even try to go. I swear I saw a spark or flash out the left side of the engine.
I took off the chain and peddled her home. (damn these things don't peddle all that easy! It works but it's not my 21 speed Townie for sure!)
Everything is tight and secure, except the case has a leak and I must be loosing some compression. The head gasket is clean, the carb is tight at both ends, the exhaust is tight and secure. Yeah I got fuel, have yet to verify spark.
But damn my top end is dynamite, a few minutes before she blew I was at 40.1 mph!
It takes several seconds and a hill but my top end is as fast as I want to go on a bicycle!
The idle is just weird, won't idle when cold, better as it warms, until at operating temp she races. If I stop for more than a few minutes, the pattern repeats.
Sigh,,if it's not one thing it's another.
