SO! I was riding down the road the other day and decided to give it full throttle just for fun. About 20 seconds in, I lost all power as if I wasn't getting any gas (had full tank). I let up and the engine idled fine and worked normally till about 10 mph, then would cut out till I let off the gas again. I limped it about 2 miles down the road till it died altogether and wouldn't start at all. Got it towed back to my house where I discovered the little vacuum line feeding my petcock was totally disconnected and was in bad enough shape to replace. The new one's on there now, and it's back to idling okayish, and will rev up, but ONLY on full choke. Without choke, I'm lucky if it revs up to about 1200 RPMs before it gives that "I'm out of gas" noise and dies. I've hit the starter with the main fuel line disconnected and it spits plenty of gas, also there's what looks like a little window on the backside of the carb that looks like it's full of gas as well. For starters, I guess I have to ask, how does this vacuum system work? It doesn't seem like it'd be designed to feed grime into the carb if it comes unattached. I don't want to speculate at all, for fear I'll throw you guys off, so does anyone have any experience with an issue like this?
