Nikki carburetor, anyone have a source for a rebuild kit?
This KS540 with a fuel pump ,has little bit of a running rich problem, it's not flooding out, but the owner hasn't had to use the choke to start it in "awhile", and at full throttle it's almost sounding like the choke is on a little, but it's not and is 100% open. I turned the fuel valve off and after a few seconds the RPMs picked up and it ran normal. This is with no air filter on it too to eliminate restricted air flow, I suspect a weak needle or float. Especially being pump fed.
