The carburetor was gunked up pretty bad.  At least one of the teardowns was to get some fuel to flow through the idle jet.  Couldn't get it to idle without choke prior to that.  I did replace the main jet when I was in there.  I guess there could be more stuff in the passageway for the main jet. . . .

What's the best way to clean these small passageways?  Poke a wire in there?  I suppose choice of solvent would depend on what's causing the obstruction.

I've been wondering if my exhaust manifold might be the cause.  Like I said the one spark plug was noticeably leaner than the others.  Is there a test for this short of buying a new manifold and swapping out the old one?

You are very talented!  Looks like my IB without the frame.  Wondering if you've considered electronic ignition.  Mine was fouling the plugs within a few hours of operation after the rebuild.  Added electronic ignition and never had an issue since.  Obviously a better spark.

Thanks for the nice words.  I did spend a lot of time on it.

As far as going to electronic ignition goes, I still think there's something wrong with the fuel side of things.  I put some "mechanic in a can" (Berryman's B12 Chemtool) in the gas tank to see if that will make any difference.  Figure it can't hurt.  Just can't get past how that one cylinder is leaner than the rest.  It runs well enough like this that I can get this tank of gas through it without fouling plugs.  Who knows maybe it'll clear up?  If it doesn't will probably end up swapping out the manifold to see what that does.

Will be exhibiting at Baraboo, Wisconsin this weekend for the Badger Gas and Steam Engine show.  

Stop by and say "Hi" any of you are there. . . .
