The stock carb needs the removal of the screws and brass bung - Motocheeze has a couple vids and there is a link to a "Hawk 250 Shen Wey Keihin PZ30 style carb tune and sprocket set Fits many bikes" https://www.ebay.com/itm/303210680840

on eBay that would suit this stock Carb.

BTW, I run the 93 octane WaWa Ultimate gasoline in all my bikes, from a 50cc stocker to a '91 H-D RoadSofa, with no issues at all. It's less than $20 to fill a 5-gallon can.

The VM22 Carb - what model carb do you have now?
What engine is in this bike?

The replacement carb is a Mikuni VM22 clone. The engine is a 125cc. This carb is much better than the original since everything is screwed together and I can take it all apart. Bike is running fine now. My first mod will be the seat - it's hard as a rock! Thanks to all those that helped me along the way.
