ive got a kohler cv740 replaced oil pan now it wont run right ive taken it back apart numerous times to double check everything made sure i removed the shims but now it runs at a very low idle wont rev up or down some black smoke in exhaust. carb was dumping fuel so i replaced it replaced fuel pump as well since i found gas in the oil, still no fix. ive also done the govenor adjustment still nothing. im at a lost it has 180+ compression each cylinder good spark. another thing to note when i loosened up the carb just a little it started reving up higher and leaking fuel thats when i changed the carb but now its still doing the same thing.
