L110 Surging at Idle

Hi all,

Lately when I start I really need to mess with the throttle to keep the thing running. RPM's go up and down. I hadn't noticed this until just the last few weeks.

Heres' what I know.

I am the original owner since early 2000's.

I have cleaned or replaced the air filter a few times and maybe the plug once.

I haven't needed to run it much lately since the snow is finally over (hopefully).

I have around 420 hours on it.
I have used it to mow a smallish yard and blow out the snow in the winter.
It has been quite cold here lately below freezing for a week or so.
I have replaced the gas filter within the last year.
I do notice that the filter is never full of gas. 50% full at best.
I have never cleaned the carb or used any additives.
The engine hasn't given me any issues up until now.

Does this sound like a dirty carb? Bad pump?
Water ice in the lines?

Should I be looking into getting some Seafood or other additive in there. What is the best way to get water out of the lines.

Any advice would be appreciated?

Pull the float bowl and see what the inside of the float chamber looks like. You can pull the bowl with the carb still on the motor but you will most likely need a new float bowl oring so have a kit on hand. JD has gone full on stupid on the price of the carb kit so I have started sourcing mine off evilbay. They more than doubled the price.
