Try screwing the needle valves in (gently!) and back out a few time,s then put back to where they were and see if it helps. If not, perhaps something's plugged. You did check for a waterlogged/plugged fuel filter, right? Fuel's getting TO the carb? HTH, PopS I'm thinking too that it's gunked somewhere. Fuel _IS_ getting to the carb (if you pull the starter rope gently with the air filter removed you are met by a mist of fuel around the choke valve). Haven't played with any fuel filters. Is there supposed to be some sort of linkage to open the choke plate? It's just that I can't see how it opens on it's own (vacuum effect???) and that would explain richness symptoms on the(new) spark plug and exhaust output popping. If your carb has a little metal "box" cover on it , then you have an automatic choke. If not, it's a Choke-A-Matic. If you are trying things out with the air cleaner removed, be sure to reinstall the stud... |
