Hello,
I am looking for some advice/help for an engine problem I can't seem to figure out.
Kohler CV20S (20hp twin) Spec 65522. Engine is on a Toro 62" cut walk behind mower. It's been this way for quite some time but this year it's bugging me enough to address it... Engine surges unless you run the choke 3/4 closed. With choke shut she's a mowing mo'chine, you open the choke it will run but spits back through the carb while running and surges and will eventually quit. It will never crank back hot or cold unless you choke it (normal kohler?) To date I have dis-assembled the carb, soaked (in gunk cleaner in the gallon can) over night blowed out using compressed air, then used a can of carb/choke cleaner and blowed it out again before re-assembly. New air filter with pre cleaner. I was thinking it's starving for fuel (since it runs fine choked) so I just installed a new fuel pump and even ran it without the fuel cap and it's still doing the same dang thing. It spits like its trying to clear its self but there shouldn't be anything in there.... I even sprayed cleaner around the carb with it running to check for a leak and no engine change. Ideas? and Thank you for your time,
Wayne
