This engine just started reving up and down. It just radomnly started while I was mowing. I put new gas in it and bought a new airfilter but that has not helped at all. I'm not sure what could be causing this. Would cleaning the carbon help?

Could be a number of things but start with the basics
.
I would make sure the fuel is getting there- filter etc. Good luck

I just finished fixing a cub LT1050 with a Kohler. 2 things to check for: 1: there is a small hose coming off the fuel pump that goes to the left valve cover. Make sure it is in the hole of the valve cover. While I was cleaning and installing the carburetor I must have knocked the one I was working on. When I was testing it out I started getting some erratic behavior and one of them was surging. Next i would check for an air leak around the intake manifold.

I would look for dirt in the carb, but first I would check the governor adjustment.sometimes they slip.

Make sure the governor linkage is in good shape, moving freely, no broken or loose springs etc. You could have a fuel delivery problem but if that all checks out check the spark, points gap etc. An engine with marginal ignition can give you some odd symptoms.

I think before any accurate assessment can be made we should know what model engine we are dealing with. Just my thought on the matter.

I agree. It's hard to diagnose over the internet if you don't know what the patient is!

Hmm that's precisely what happened to ours also! And I believe it's the same model.

Ours is being serviced (every other year, between times I do the oil and filter change) and I've asked to have the "hunting" fixed. I will try to post here what they tell me they find and the fix $$ I suppose😟
I ran it again before I took it in and with more (fresher?) gas in the tank a large part of the surging/hunting subsided.

Our CC 1046 is back, finally. The mechanic found nothing wrong at the carb. He did replace the fuel filter and fixed a slight oil leak (it was more unsightly than serious). Runs like a champ again so I'm guessing it was a combination of filter and something falling into the fuel probably when I topped up the tank?
