New flywheel won’t start

Please take your time with me….I’m new to the forum and still have a lot to learn.

I got the kart from a cousin who rebuilt it and have been learning as I go. It has a GX200 clone.

As I was driving last week I heard a bang and noticed an occasional sputter so I turned back to the house and shut the engine off. It didn’t have any issues on the mile return to the house.

I thought maybe I ran over something and also couldn’t find any external signs of damage right away.

I tried to restart the engine but it wouldn’t start.

As I removed the pull start cover I saw the issue. The magnet on the flywheel had broken apart and was in shards.

I did some quick google searches and thought buying an inexpensive one aluminum one on Amazon was the best choice and it had good reviews.

I can’t get the engine running now. I have fuel but I don’t seem to have spark.

Help please

Is the picture of the flywheel the old one, or the replacement?

New aluminum flywheel installed with pull start removed

With the broken magnet? That’s the old one. I’ve just posted a photo of the new one

First, do you have a link to the flywheel you bought? I’d be concerned about the quality, rpm rating. How did you determine if it has the correct ignition timing. Is there a magnetic field on the new flywheel?


Everything works fine now……when I reinstalled the cover I ditched the on/off switch and didn’t realize I shouldn’t have grounded the wire.

It actually runs smoother now and seems to have more power off the line and at low rpm.

I bought the flywheel off Amazon for $38

While I had it apart I installed an extended starter nut.

I also cut the front off the flimsy pull start cover and welded on a new one I made on the water jet.
