Small Engine Troubleshooting Problems? Ask a Mechanic Now.
The initial adjustments on the carb are as follows. The main jet in the bottom of the carb bowl should be set to 1 1/2 turn open from lightly seated. The idle needle on the side of the carb should be 1 turn open from lightly seated. This should get you started and running provided you have no other problems. The final adjustments are performed after the engine has reached operating temperature. Run the engine at full throttle and turn the main needle in until engine runs erratic and note position then turn out until engine runs erratic and note position. Turn the screw back in midway between the two points.
Return the engine to idle and repeat this process with the idle jet. If the engine hesitates when going from idle to full speed when accelerating quickly then adjust the main jet with engine under a load 1/8 a turn at a time until it accelerates smoothly.
That's exactly what I needed to know, sounds like the tech manual answer and I'm sure it will work if the carb doesn't have other problems.
Thank you very much my friend.
