Hi Greg,
My Uncle, who was a really great mechanic, always
taught me ( and emphasized
heavily!) that when troubleshooting :
1)compression, 2)ignition, and
3)carburetion. But the important thing is
always in that order, or you can
waste a lot of time accomplishing nothing.
On
ignition, pulling spark plug wires (carefully, not grounding
yourself...make
sure you know how to do this) one at a time may indicate which
cylinder(s) are
not firing.
If you "pass" compression and ignition, you might check for a
sticky needle
and seat on one of your carburetor floats who's bowl may tend to
go somewhat
"dry" after sitting and then"shake loose" and fill up after the
engine starts.
You might also check for a slight intake leak that seals itself
as the engine
warms. If you can work "fast" after the engine first starts, a
stethoscope or
hose to your ear listening to each carburetor's suction might
give you a clue.
Although not a common issue, checking your fuel pump pressure
cold might also
be in  order if everything else seems ok.
Hope this is
helpful, and good luck!
