RE: Hard outside loop and engine stalls
Your engine is mounted up right? You have it adjusted just a LITTLE on the rigch side. one or 2 clicks leaner and it should go away.
If the engine is relatively new... it may not be cureable until the engine fully breaks in. Some engines thats over 3 gallons of fuel. The 2 8-oz tank break-in is really just starting the brek-in process.
