Have cleaned the carb and needle, there seems to be no problem at all with the fuel delivery...

Try swapping the spark plug holder (it's called something else but I can't remember the name right now) with one that you know is working. This was what was wrong with my 80 puch that drove me nuts about a month or two ago. I think the holder is insulated and has a set resistance (1k ohms?) which can break down and wreck your spark.

Ok, will try this out.

Tail running lamp may have poor contact, make sure lamp is seated w/ clean contacts. Broken filament???

man we did never look at the taillight, and if i remember correctly, that entire thing was hanging on by a thread when we first started to have huge problems

the rings should be fine, its got 150 psi,

Wait, it's what?

I still think you got to have a working rear 'run' lite. the LAW...

A defective horn also inhibits ignition. You can tape the two horn wires together I had too once and left it so.

Threw away the horn, it was no good.

Maybe I am a little green to the world of electirc systems, but how does the tail light dictate if the ped will run? Just curious...

Thanks!

Update:

The horn/headlight wiring was the culprit. Fixed that up and she's running like a champ! Well, did for about two hours.

It's definitely a fuel flow thing. Electrical is fine, with the exception of my ignition switch not working at all. Spark is strong and consistent.

If I clean the carb out, she runs well for a varying amount of time usually not long, then will start bogging down, backfiring, and stalling out. It gets progressivly worse, til she doesn't recover from the stalls. I had her out for about a 1.5 mile round trip, got home just as she died completely. I immediately pulled the plug and it was bone dry. Clean the carb and the process repeats itself.

I figure the tank is super nasty and is the cause of the trouble. I used some concrete cleaner in the tank to clean it out. Hopefully it was the right stuff. More on this in a sec. I soaked the tank for 20 minutes or so, then flipped the bike so it would soak the top of the tank. After flipping the bike, it took me a couple minutes to locate the slow drip I was hearing. Dark reddish brown oil was dripping from the engine into the body of the bike and out the seat mount. I flipped the bike over immediately. I probably lost about an ounce or so of fluid. Anybody know what this was? I'm afraid to start the bike without knowing what it was and if I should replace it.

When I drained the acid from the tank, I was worried. I was expecting it to come out like liquid death with chunks. It was only light brown though. Drained it all out and started hosing the tank out, again the water was not as nasty as it should have been. After rinsing a bit, I let it drain out and tipped the bike over to get the last of the water out. Nothing was coming out, but I could still hear water in the tank. Hmmm. Tilted the bike way over and shook. Sweet Cuppin Cakes. I found the Chunky Death Nuggets. Spent the next half hour shaking out the Nastiest Stuff I Have Ever Seen. Chunks half the size of my pinky nail. Something long and squiggly and LONGER than my pinky.

Hopefully this will help, but I will definitely need to do this again, maybe with a stronger acid. The bike is going to dry out over night, then I'll try her tomorrow. Any ideas about the stuff that leaked out? I don't want to fire her up without knowing if I might damage the engine.

Been drying since yesterday afternoon and has another 5 hours in the sun or so, then I'll see if it is dry. I think this is a one speed, but not sure. Any way to find out by looking at the bike?

Thanks for the help!
