How can i tell if the fan keyway has moved throwing the timing off?

You have to disassemble the fan housing to get to the flywheel but I doubt the woodruff is sheared.

What the problem making think it could be sheared?

I can't get the blower to fire at all. I bought it used. It has spark,compression 90 lbs,fuel. I even put gas in after taking the plug out. I also checked the muffler for a blocked spark arrester. Any help will be appreciated. Thank you. The blower is only a year old.
