It accelerates decent at first then begins to hesitate. It will then back fire and it seems to get the power back. I changed plugs, wires, cap, rotor. I run recreation gas which is fresh. Same result. Amy suggestions? Thanks!

Check (or change) your fuel filter, and make sure the float level in the carburetor is adjusted correctly. A too-low float will let the carb run dry or very lean on acceleration, then catch up and pull well as the float chamber refills.

Do you know of anyone who can rebuild it reasonable? | | | | | Joined: Apr 2005 Posts: 7,441 Bolter | | Bolter Joined: Apr 2005 Posts: 7,441 | Get a kit and give it a try yourself. It's not as complicated as you might think. Take pictures of every step as you go.ðŸ‘ðŸ»

Just make sure all the air and fuel passages are completely clean and blow a lot of air through them with a high pressure nozzle from an air compressor. Then reassemble everything in accordance with the instructions in the kit and make the adjustments they recommend.
