Do you have the H and L adjuster screws on the carb? If so, then normally I'd back out a little bit on the L (low speed side of carb) The instructions for adjusting carbs, years ago, on 2-stroke, say to back out on the L when motor will not rapidly rev up. Most 2-stroke carbs have these 2-jets. The L is for gas to pass to motor with butterfly throttle plate closed. When opening throttle plate, there is a sudden rush of air, at first, and this L adjustment is allowing enough gas to pass for motor to begin to rev. up. Then the gas will also flow through another small port H, usually a small brass tube in the venture area (smallest diameter section of carb). You adjust the H with the throttle wide open, motor revved up. Turn either in or out slightly till highest RPMS reached, motor smooth and fast, then turn H out about 1/4 turn. The idea is to run motor slightly rich for highest HP when under load (cutting). Hope this helps

Hello:
Have you Removed the Muffler and Checked the Exhaust Port and Muffler for Carbin Restriction?
Remove the Muffler and Start the Unit. If the Operates Correctly, then the Spark Arrestor Screen is Clogged and the Muffler/Screen Requires Replacing.
Make Sure the Exhaust Port is Not Restricted Also.
Hope this Helps.
Good Luck
Respectfully
John

I resolved my problem by taking apart the carborator and cleaning it. There were clogged passaged that had stuff come out of them when I used airisol carb cleaner to blow them out. I only had to make one gasket the carb mount gasket which is pretty basic only 5 holes.
It ran for the next 3 hours, ran fantastic!!!!!!

Start with 1 turn out from bottom on both and adjust from there as needed. The screw closest the engine is low speed mixture adjustment and the outer is high speed mix. adj. Hope that helps. Dwain
