OS 1.08 BX-1 Keeps starting backwards

My OS 1.08 BX-1 Keeps starting backwards. 6/7 times it will start backwards instead of the right direction.

When it finally starts the correct way i give it gas and it slows down and flips back and starts running in reverse.

I have a "Throttle stop screw" on this motor and have adjusted it so that it does not restrict the carb from opening and closing freely.

What can be going on here?

Low End Setting?

Almost sounds like your low end needle setting may not be dialed in.

Sounds like it back fires hard at starting... is your fuel mix off? Does it need more nitro or oil?

If it was a sparkie I would say ignutuon timing was wrong .In this case try a cooler running plug and see if that helps
