Seems to be the same size as the two stroke was

It's got to be something simple, those things usually go pretty good.

Yep old trans is 10 teeth as well.

Try running it without the fuel filter. Sounds like it's going lean.

I havnt tried it sense i flipped it around will let you know in a couple of hours. I did notice when i first installed it upside down and turned on the gas it didnt even get past the filter on its own.. i hope it was that. I dont see a air to fuel adjustment anywhere either.

Also i drained my old gas tank with two stroke mix, i let it drain completely and added new gass, that risigual wouldnt do that would it , i am so baffeld

 

[Vikingimike01]

is the fuel tank getting air? no vaccuum?

 

[Danaman117]

Actullly it is.. its the old style for 2 stroke with the vent.
