I picked up this Mini Chopper and was told it needed a Pull Starter. After some tinkering I realized the wiring is hacked and the electric starter wasn’t even hooked up. The electric starter does work when hooked to a battery. I also have a 49cc from a Zoom Pocket Bike but the crank is different and the starter pawl and pull look different.

1) What size woodruff key hold the crank and starter together?l
2) Is this starter assembly correct for the 43cc?
3) How does the starter pawl and pull go together since the pawls all seem to screw on the crank shaft such as the 49cc, then the pull start bolts on.

Overall it just seems like something is missing here. The bike it self just needs some electrical work which isn’t a problem but this starter issues has me confused a bit.

Well so far this is all I can come up with:

I need this Bolt, not sure if I need 2-1/2” or 2-1/4”. The larger diameter end should thread into the center of the Starter while the Starter Pawl threads onto the smaller diameter of the Bolt

Is that Pull Start set correct as I’ve seen round Pawls instead of the oval shaped Pawl?

I am however still trying to find the proper size of the Woodruff Key.

I would start by getting your hands on the shank bolt and work from there.

A note of caution some of those starters spin the opposite direction I have put them together before to find out that the starter was the wrong one.

Shank bolt ordered and should have it in a few days.

Not having much luck with knowing what Woodruff Key, Pawl or Pull Start I need so thinking about a new engine instead. Will the link posted be a good choice?

What's wrong with the pull start you have pictured???

If you're going to buy a new engine you might as well get one without the electric start.

The motor in the link is both Electric and Pull Start.

I can’t verify if that’s the correct pull starter or not, was hoping someone would chime in letting me know if that one will work and if I need a spacer that I’ve seen used as well not to mention what size for that Woodruff Key

 

[MrKitty]

The mini chopper has the long starter well most of them did not have the spacer but the electric starter is completely worthless and normally fails after a very short time most people just break the magnets out and remove the brushes and stuff it really robs a lot of power you can use either style of starter the GS moon or brick it just has to match the pull starting mechanism and that is why they sell them together oem on the pep boys apc mini is brick the key is the same on the Cagllari Daytona engine but check the measurements Woodruff Key - Cag 47cc - 49cc

The pull start looks fine. The electric starters are terrible and will eventually cause problems. I believe all the woodruff keys are the same.

Thanks for the link on the Woodruff Key! I am not worried about robbing it of power since my 4 & 5 year old ride these things and have 110cc ATV’s if they want to get crazy lol. I’ll check the measurements on the Key slot in the morning to verify. Thanks for the help….

Got the following ordered and should have them tomorrow, hopefully it all goes together. As soon as this engine is ready then it time for paint and redoing the electrical.
