[Farmall] H carburetor questions

[Jim Becker]

Kenneth,
I haven't worked on an H carburetor so I can't answer any specifics.  But I 
didn't see any other replies to this.  Maybe it got mixed in with the 
transmission leak question.

Generally, the difference between gasoline and multi-fuel carburetors is in 
metering.  Jets, air bleeds and the like are the major differences.  Some of 
these differences are in small parts assembled into the carburetor, others 
are machined into the bowl and throttle body (main housings).  On some 
engines, the multi carb will have an adjustable main jet while the gasoline 
only is fixed.  Basic carburetor kits usually contain gaskets, float valve 
etc. that are the same in both versions of the carburetor.  The complete kit 
might include parts (like a jet) that are sized to one application or the 
other.  So the parts in a comlpete kit will usually go right into either 
carburetor.  They just won't be right.
