Re: 82 express runs dies out

Brad, I'm not an expert, but I keep learning, and reading the posts. I owned a 1978 express. It was a good bike,

Mine finally died, with very similar problems. I alwasy assumed it was the carb that had gone bad. I had a hard time finding parts, and the carb never made it back onto the bike. That was the end of that.

One thing that sucks about fixing mopeds, is it always seems like there's a moment of zen when it runs just fine and everything is perfect and then blubblubbuhbuhbuhblaaaah the moment of zen is gone, and your moped won't run.

Hey my puch did that, and it turns out the float was bent, and it was shutting off the gas too early. check the fuel flow from your tank. Clean all filters, and then try it.

When it dies and won't restart, splash a little fuel in the intake and see if it runs for a moment. If so, you need fuel.

Check flow from the tank and make sure you are not getting crud from the tank.

Make sure the gas cap vent is not plugged.


Re: 82 express runs dies out

I had the same problem 2 days ago, I tried everything, then i found that the exhaust was clogged.

Mine would idle fine, then it wouldn't revv up.
