Nothing wrong with that flywheel, a lot of us on the Cag China clone Blata's cut off every other fin, to lighten it. Break off the 2 fins 180 degrees a crossed, clean up the whole flywheel and magnets w/ sand paper and the coil arms too. Re-set the coil gap to .020", .5mm. Not sure if you have the 4.2 or 6.2 horsepower, N!pples will know.
Your in England right. Search for Petrol Scooters, there in the UK. I am in USA in California and I bought a few parts for my Blata clone 50cc water cooled China C1 there over the years.
Also, search eBay.UK, for 39cc air cooled Blata parts. Parts are not cheap, maybe $50 for a new starter housing. I have a 39cc air cooled Polini 910 Carena. The Blata was made in Eastern Europe by Pavel Blata. My polini is made in Italy, both are mini moto bikes.

Its a Blata 2.5... The Blue Bird is the paint scheme.. They did many paint schemes on these things but all the same frame and engines.. Yes 39cc

The 2.5 model has the smaller 4 inch rims and 14/12 Del Orto
the 2.6 Model has the 6.5 inch rims different brake mounts for the wheels to fit and a 14/14 Del Orto Carb.. Both 39cc

Do what EPR says and take the 2 opposite fins off the fly wheel.. It should work.. Or look at Midsouthminimoto...

This is a img link in those IMG Tags I mentioned..

No problem.. After looking at the pictures further you might have a problem here...



The center crank stud looks stripped and some kind of epoy holding it on?? Those prawls on top should both have springs that keep them towards the center to grab the starter claw and then spring out when the engine starts and flywheel starts spinning fast...

If you take off that epoxy off can you get a Metric Nut on it??? You might need a new crank and flywheel with starter prawls...

Pocket bike madness begins... ;) Might want to find a cheap 2nd to steal parts off of...




Mid south doesnt seem to sell just the crank... Sure its not cheap...

I was wondering what that white stuff was, I kept looking for the crank nut but could not tell from the photos. Got to have them springs and the starter levers. Them people want €216, $250 US for a 49cc China Cag engine, wow, they probably paid $30 or $40 for it. If there is a stub big enough off the crank end, might be able to put smaller threads and a nut.
