I bought that same ebay carb. 32mm CV with elect enrichment? For a GY6? It uses the same type of jets from the early Harley's, but the dealers don't carry them. I found them online but scared to pull the trigger.....at $7 each, can't really afford to buy the wrong ones.
That's why it's sitting in a box in my garage.
If I were you, I'd get a Mikuni.
