new top end

Just put a new top end on my blaster (eBay kit) . I have plent of compression and spark is good. Carb is clean and clear with pod filter. Fuel is reaching the carb from the tank. Here’s where I’m confused: I poured some gas in the cylinder and it still didn’t fire!!! Possible crank seal??? Any...

First time making a post. But So my chain popped the day while riding and cracked the case, still rode it with the crack for awhile after I just would add oil before every ride. Eventually I blew the top end. So I ordered a new top end kit off eBay which came with new gaskets, new cylinder...
