okay my bike was not idleing so after checking everything else I decided to move the stator plate. First I advanced it.

The bike still would not idle and I heard a slight nock so I put it back to the original setting. no idle so I turned it a little the other way, my puch back fired. I set it back to the original setting. won't start. move the stator plate either way and it won't start. I took a closer look and now the points are opening when the piston is all the way in. haven't messed with it much since. I have been researching how to set my timing. I'm going to buy and ohm meter I guess and sit down and try to get it right. still I don't understand much about timing after all I have read. I would give my left nut to get this bike running(It's my gurlfreinds puch and she hasn't been able to ride with me so I won't ride with out her.)Anyone who reads this sorry post, Thanks.

Sounds like you sheared the flywheel key. Take it off and look.

took off the fly wheel and I put it back on. now it starts back up with a few kicks. still will not idle and stalls on a load. it has new carb, clean exaghst, nice fat spark. I think I ajusted every thing on it. I think I've read every post on this subject.

Thanks alot Ron for the sugestion.

You mentioned you have a new crab, Is your carb a stock Bing carb?

Does it have a choke stem that you push down? If it does, if the choke stem is pushed down, it should come up when you twist the throttle.

Try adjusting the throttle cable length where then cable enters the elbow on top of the carb. screw it out from the pipe a bit until the engine runs at a higher RPM.

Also screw the idle screw on the side of the carb in or out to fine tune adjust the idle.

Lube the throttle slide under the throttle grip on the right handle bar. The throttle should snap back to the idle position if it is working properly.

Check you clutch adustment to make sure it is not slipping.

Check your tranny fluid. 1 speed 4.5 ounces ATF type F.

, 2 speed 9.5 ounces ATF type F.

DON'T overfill if it is a 2 speed or it will bog down under a load.

Thanks Zippy but I did all of that already Like ten different times. still no luck.

I bought a new bing carb from mopedwarehouse.

I have Checked my clutch cable

I'm not sure what slipping means. When I realse my clutch it should return all the way, right?

Thanks Again.

OK, lets get serious here. You have a ped that goes from firing to "the piston is all the way down when the points open". You take the flywheel off and replace it and now it is running again somewhat.

You don't mention how this magic happened, or whether you ever found a flywheel key. Surely you must wonder how this cured the timing.

Give us a little more input please.

I'm an idiot for not tightening the flywheel

Sorry about being so vage.

When I originally ajusted the points I took off the magneto flywheel. I move the stator plate. it backfired. so I took off the fly wheel and moved the stator plate again. back to the original setting. now it won't start.

after your suggestion, RON, I took off the fly wheel to look for anything strage. I noticed nothing. I made sure all my srews were tight. when I went to put back the fly wheel the nut that held it on seemed stripped. I would turn it and the flywhell would not tight down. I took off the nut again and just looked at it. I pushed the flywheel on firmly and the put the nut on making sure that it when on all the way and that the flywheel was nice and tight. Now it starts but still won't idle.

I think that I did not have the flywheel on correctly the first time.

Sorry for wasting your time guys.

ummmmmm

There should be a key on that shaft. The nut will hold it in place, but it will still rotate if you don't have the key there. The flywheel has to go on ONLY ONE WAY.

The key is a peice of hardeded steel that goes in a slot or hole on your crankshaft. There should be a slot machined on your flywheel's center hole, to slide over this key.

I lost my key and now I'm a monkey

I know the slots you are talking about and I can't find the key anywhere. I think it got lost the first time I removed the flywheel.(a month ago).

some well-stocked hardware stores have tham, or you can call motorcycle, or small engine repair places to find one. bring in the flywheel to get a match.

Thank you mbartel. I was 99.9% sure this was his problem, but I have never owned a Puch and Motobecanes do not have the points cam attatched to the flywheel.

If it is a woodruff (semi-circular) key, you need the diameter too. Try to find a coin or something similar that you can fit into the rounded slot in the shaft, then mark it at about the depth of the flywheel groove. This will give you a good place to start.
