Have you performed a leak down on the engine?

Evan good to hear you're making progress. The Duncan jetting guide is very useful, but this flowchart is also a great way to check on your jetting (especially the idle/air/pilot circuits).

To make the tester go to your local Lowe's & pick up a Shark Bite test pressure gauge p/n 25489Z(aisle17/bay 23), steel 3/4" -1/2" threaded reducer, steel 1 /2" close nipple & a pvc 1 1 /4" slip to 1/2" npt reducer. Then get a 1 1/2" rubber pipe plug for the exhaust flange. Also grab some Teflon tape & Teflon paste if you don't have both already. Clean all the fittings than make 2 wraps with the tape than do a coating of paste & according to my good friend who's a plumber you'll have a leak free seal. Make sure that engine is sealed before attempting to tune it.

I did get it to idle and I did ride it just in the yard and it had full power, almost no low end bog and filled the place with smoke and almost instant power wich in my mind it is jetted and tuned almost perfect for not trying to make it perfect. I will do a leak down test but with how it's running I'm sure that it has no leaks but I will double check
