Yeah take your punishment with a grain of salt, you’re a dummy that don’t read posts or search like you’re supposed to do.
You tried a couple Obscure jets which none of Them are right,
One jet and or needle and or atomizer wrong and your bike will be a dog when you need clear clean, crisp jetting throughout the range!
Most times a 78jet is right but that is with the real 217 atomizer and Single embossed ring needle which a clone doesn’t include (my opinion you should throw away the carburetor and get a real one) plus you didn’t time or service your magneto like your supposed to do before you do anything,
Read this and follow it perfectly or don’t and fail https://www.mopedarmy.com/wiki/Puch_timing
I’m sure you didn’t Rebuild your engine with new seals, tune your clutch, Regear and you’re probably not running a head temperature gauge either not to mention ya didn’t service your brakes, cables, bearings nothing!
You just Got a Moped and wanna go 50mph without learning to tune stock parts first,
With that mindset you be playing around with this bike forever and flooding these forms with your problems So going by what you said you probably should get like a motorcycle or scooter or something with monthly servicing and a guarantee Because a DIY Moped will never be good for you,
