My e50 with a za50 stator magnito

Johnnie Walner /

My bike will run but it's just runs full rpm at idle and I dont know what whould cause it. Maybee timing maybee the za 50 stator magneto flywheel I put on before I found out it was a compression issiue should i switch it back to the original points and magnito setup? Help??

Cdi? They fit either engine, just pick up is flipped to one side or the other. Search treats cdi and itll give you a picture on what to do.

Re: My e50 with a za50 stator magnito

high idle doesn't mean your ignition is wonky, its airflow or airleak.

1. ensure throttle slide is all the way down,

2. ensure no air leaks from carb all the way to combustion chamber.

look up how to find air leak

Re: My e50 with a za50 stator magnito

Yeah probably an air leak causing your issues. Start it up and do a air leak test. Spray some carb cleaner at all the connection points on the top end. Carb and intake included.

Re: My e50 with a za50 stator magnito

Like these guys said. You are describing an air leak.

The ZA and E50 flywheels are not interchangeable. Without the correct flywheel, your timing will be whacky and basically makes hunting down airleaks pointless.

Re: My e50 with a za50 stator magnito

Dillon,

I thought the same thing but the issues described made me think there is an overlying issue. I was surprised the bike even started with the za50 setup. They run opposite ways. But I know if it is a cdi you can flip stuff and make it work. I have no clue how he would have gotten za50 points to run.

Even though they run reverse direction, they are not 180* out, they are close enough where you could probably get it to fire, if run very poorly.

If you are insistent on running the ZA flywheel, you'll need to lap the weight to the crank and run keyless, at which point you might as well just buy a real E50 flywheel and not have to worry about setting it freehand every time you need to pull it.

Posted this probably a dozen times already, maybe somebody should put it in wiki, The stock Stator for both engines are the same but not the flywheels,

These are differences in the two flywheels! The ramp on flywheel that snaps the points open for timing is almost like a camshaft on a car by the points fiber follower hitting it on the steep side of the ramp

The opposite side is a less steep of a angle ramp so the points can gently go back down,

Using the wrong flywheel makes the points kinda/sorta open on the less angled side somewhere and you’ll never get it to run right/make a good voltage when the capacitor discharges.

You need e50 flywheel which is the one on the left (unless the pictures got reversed)

Re: My e50 with a za50 stator magnito

Is that a late model ZA magneto in your first pic? I've never seen a stock Puch magneto like that...

edit: Oh those are tomos points! Yeah they are meant for counter clockwise, if you have those set on the Puch E50 woodruff key there's no way it's going to be timed right, and to Ken's point the cam cutaway will be off for clockwise motors. (edited)

Re: My e50 with a za50 stator magnito

Can confirm, they'll run with the wrong flywheel but you'd immediately hear that something is wrong, lots of clacking as the wrong side of the taper slams open the points

No you must have the wrong magneto mike or I don’t know?

All za50s I had with stock points ignition for like years (78-1986?) all had the same/have the same cam Profile on flywheel,

I had probably 5-6 dozen Za50 bikes/engines and the flywheels all/were interchangeable as long as it says 5/10w-21w and has Counter rotation arrow, They all will work,

It’s possible someone used a Tomos flywheel On a za50 maybe.

Mike's asking about the OP's post.

I was just gonna say, that ain't no Puch flyweight.

I'm gonna guess this dude is trying to run either Tomos Points, or Tomos CDI.

Re: My e50 with a za50 stator magnito

It's this one:

https://www.treatland.tv/puch-ZA50-stator-plate-magneto-points-p/puch-za50-stator-magneto.htm

looks sorta like a tomos one but treats calls it ZA, maybe a china clone?

Re: My e50 with a za50 stator magnito

@Mike, you're right. I have never even bothered to try those.

Also, to the OP: Did you not read the comments for that item? There are only three and they could have saved you wasting your money.

I mean, 5 minutes of using the MA Search bar could have also done that.

Yea you were dead on it ran like crap and it wasn't lapped correct causing it to jump timing i switched over to this setup similar to the original picture posted and runs pretty well. But now I can't get the headlight to work on this one i think the coil doesn't supply enought wats to run a headlight bulb and running and tail light all at once. Whe I turn the headlights on the back running light cuts off. When I turn it back on lback lights work again. The za 50 flywheel was causing engine knocking noises and wouldn't run for more that 3 minutes without jumping time but this one ive put several hundred miles on it in the day time. I really need to fix the headlight to work. Can I take the light coil outta my original flywheel that came with the bike and put it on the one below in the image? Sorry for the late response. And I appreciate all the help i did away with the za 50 fluwheel setup maybe I can use the light coil off the za 50 for lights or the old wine that came with the bike? Anyway thanks everyone!
