Armchair diagnostics- hard warm start

[Steve Northrop]

Could be the battery, I replace mine every 2 years because it clears up 
"mysterious" ignition problems. Have you checked the carb boots? Tight 
against the head and tightly clamped around the carbs? Do you have the caps 
off the pilot screws? Start turning them out 1/2 turn at a time until it 
starts easier. BTW, don't touch the throttle on cold or hot starts. Pumping 
the throttle does nothing because there aren't any accelerator pumps on the 
carbs.
