Is there a difference in a marvel schebler carb off a 49 B and a Zenith carb off a 39 B? Can they interchanged? Thanks! |

39B won't start with hand crank. Switched carburetors between 39 & 49 B's, 49 runs fine with the 39 carburetor, but 39 still does not start. After a few turns with hand crank gas will drip out bottom of carburetor. Need some advice or ideas on what to check. Thanks! |

Each hand crank tractor seems to have it's own preferences for starting procedure!  . My '39 B with Zenith carb likes gas on--one pull over with full choke, then choke off and one more pull over and it's usually running. Depending on outside temperature, I might have to add a little choke 'til it warms up a little.Too many cranks with the choke on will usually flood it and then it can be a devil to start!!
