Once in a while she will start first kick, other times it can take 10-15 kicks. I'm worried she may need a top end rebuild, not sure... I'm just going to ride her and see what happens.

Play with the idle mixture screw. Small singles can be picky about the setting, and won't start well unless it's in just the right place. Usually the starting point is about 1.5 turns out. Some carbs will have a idle mixture screw that adjusts the air bleed, others will have one that adjusts the fuel bleed. It's nice to know which you are dealing with. Turning an air bleed in makes it richer, turning a fuel bleed in makes it leaner.
