My mule will accelerate and drive very well when cold but once it's hot it will intermittently run horrible. The mule will more times run poorly then actually accelerate.
Here is what happens, I take off and step on the gas, and the mule just bogs and barely moves. If I hold the gas enough after about a minute or two it will just take off.
My old engine threw a rod so I had a spare magneto that I slapped on but to no avail.
The carb is spotless, and all the jets are clear.
