18hp Kohler exmark

I have a 18hp Kohler on my exmark lazer z hp. IT started idling funny the other day, and I had to leave the choke on for it to stay running. I cleaned the the air filter and the carb, but it still doesn't run right. It idles rough now but I don't have to use the choke. My local dealer thought that I might have junk in the gas so I tried fresh gas but that did nothing.

It feels like I'm not getting enough fuel, but I'm not sure. Also, when I go up hill it loses all power. If any one could help me it would be greatly appreciate.

Check the simple stuff like the fuel filter and float level. If you can feather the choke and find the power comes back, you know it is a fuel starvation problem. You may have a weak fuel pump or bad intake gasket making it run lean. If you have that pulse fuel pump you can check to make sure the pulse line is in good shape and not leaking. If you have the mechanical pump on the rocker cover, I find they either work good or don't work at all.
