The Kohler 17.5 hp is a very good motor. I have had one on my GT235 for years with no issues. That said you likely have a dirty carb. Take apart and clean carb with new needle valve and bowl o-ring. That motor has a metal fuel feed cross over to carb. Add a 2 stroke trimmer style screen, the red thin style, after metal tube and before the carb. Make sure there is the usual filter before pump. You should be good to go...
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?
Thanks
Mark

Doesn't matter where you buy as long as it's Kohler. Once issues are worked out, fuel needs some sort of stabilizer/additive
if gas is not used up regularly. I use Star-tron fuel additive with no issues. But it's not a cleaner.
