Here are a few things to check.
1. make sure you have a minimum 4-5 psi of fuel pressure. 2. when the carb was rebuilt, do you know if they installed a new excellerator pump in the carb as well as a new pump spring? This will cause serious issues with hard starting. This not only brings fuel into the carb it helps maintain it in the bowl. If the pump is wore out, or if the diagphram is bad, it will leak down causing a hard starting condition.
I hope this helps.

next time you go to start it 1st take off the air cleaner, hold the choke where it is & pump the throttle several times and see what you have for AP shot (amt/duration) then let go of the choke & see where it closes at. A ballpark figure on auto choke setting, it should be lightly closed @70F.

I'm wondering how the carbon buildup was causing it to start hard? I could see it causing poor warmup if the head crossover is plugged. My heat riser passages are plugged (stock dd 318) which is killing my gas mileage but it does start flawlessly (eddie 1406 600). The more info the better as I'm lost on this particular prob & if it wasn't so cold I'd ride my bike, it's that bad .
