Help with jetting

I have a stock 47cc sachs, 28mm header with a slip on jammy pipe and I made up a forward facing intake to fit the 15mm bing with a mesh cone filter. It runs alright but could run better. Didn't change the jet when I put it on and I believe it's a 82. Can anyone give me an estimate of where it should be jetted?

Try smaller if rich

No magic # just experiment and have fun

Does that seem like too big of a jet? I'd say if anything it's running lean. I know there's really no "right" jet, just trying to see what people with similar setups are running

Real bings come with a 82 jet and most times 78 jet is fine for my puch piston port kits , reed kits run a higher jet .
