Husky Lawn Mower runs Rough

Hi group!

I have a husky 51d lawn mower (sprint 3.75 HP motor) that starts on the 1st or second pull. The engine will run at full throttle and cut grass fine for a few moments. Once the engine appears to warm up, it then runs rough. The engine won't hold a steady RPM, rather, cycles between high and low. This causes less power and a less than perfect yard. I am sure this is an easy problem for the masters in here.

Here is what I have done:

Replaced Spark Plug
Replaced Air Filter
Removed Carburator and sprayed it with Carb and Choke cleaner
Ran out the gas and replaced the gas with brand new gas

Out of ideas,

Sipacate

It sounds like the engine is running a little on the rich side.

Hello Sipacate!

You were so close when you removed the carb and cleaned it, but you didn't install a new diaphragm, right? That is what you need to solve your problem.

Let us know how it goes!
