Well mechanic did a plug reading, new plug, found it's not rich but lean. Adjusted mixture screw out and engine starts and runs better, BUT, if you stomp on the gas it dies. Bring it up slowly and you can get full throttle. This carb has throttle plates, not a slide like M/C carbs. Still in the shop. Going to check valve adj next and then compression.

Mechanic that changed the carb said that it is running rich. Screw has a limiter on it. Any ideas on how to get it off and lean out the carb?

Help Please! Last year my Mule started running bad and was hard to start. NOT a battery or starter problem. I replace the carb with one of those cheap Chinese carbs from Amazon. Problem got worse. So, I replaced the fuel pump, one from Kawasaki, fuel filter and lines. Then replaced the fuel pump line to the engine. Finally bought a Kawasaki carb. Everything was ok till I filled the gas tank with fresh gas then it started running bad and hard to start again. The tank is clean. Gas is fresh, AGAIN. Filter is new. When running it has an occasional misfire. Managed to burn about a gallon out of the tank. Runs better. Replaced the gas cap in case it wasn't venting. No change. When running, if you try to go full throttle, it bogs down. The gas is good. I use it in my mower with no problem. The stater was replaced about one year ago and the flywheel cleaned inside. Still seams like a fuel problem but I'm at a loss. It's going back to the mechanic shop today. We use the Mule every day, live on a farm. It's never sat up. It has 1045hrs on it. New battery and starter. Any ideas?
