imn0tnorml - It sounds like you may have your engine TOO LEAN. This is called "lean bogging" especially if you know the engine is running hot!

What we suggest is to reset the needles back to the factory defaults and go from there. Here they are:

Default:
Top: 3 1/2 turns out
Bottom: Flush with side of carburetor.

After break in:
Top: 3 turns out
Bottom 1 -1/2 turn in from FLUSH.

Try this out and let us know how that works.
