Hard starts after running

@TrailBeast is applying logic. If base timing is actually anywhere from 0 to 16* BTDC, then its probably not causing the hard starts, and even up to 18 or 19* I would not expect that to be an issue.
Heat issues at start are probably not directly carb. Its either too much vaporization or too much liquid fuel in the intake. The latter can occur when vapor in the fuel line can't burp without pushing extra fuel into the bowls - overfilling them to the point they spill or drip out the boosters. The former is kindof the norm with an open system, and we just need to learn to manage it.
