that is a carb. issue on a warm restart,its to rich on the bottom and the added air flow from opening the throttle will lean out and help starting the sled. first easy thing to do is turn up the idle a bit, not much this will help but most likely be changing pilots jets and or air jet #..

Don't panic until you at least get the carb issue figured out. It's possible you have a cylinder flooded, flooded cylinders will seal better than non-flooded and show slightly higher compression numbers. And because nobody has ever had a compression gauge calibrated I wouldn't worry about anything over 100 if it runs good.
