The Spree petcock is the same one the Aero 125 runs, so I would say if the screen in the tank in clear that yes it should flow plenty of fuel.

Screen is above the petcock inside the tank.

Did you replace the fuel lines? If not all you work will have been wasted. FYI moving the need should not be necessary. properly adjust the idle mixture and that does NOT mean set the needle to the spec listed in the manual. You have to adjust the d*** thing.

the line is new. I have my idle * 2 turns out, I just need to tinker with it, and get a new plug. The ones thats in there looks like it was use for break in.
You need to read the manual and see how to actual adjust the idle mixture. Only a total amateur would think you can just set it to a specific number of turns and leave it. :jack:

measure the belt and ask the experts if you need a new one. i think it was on the worn side and a new one should give you the extra mph.
im glad you are having fun with it. good luck
