'91 n/a convertible won't start
 

Help me out if here if anyone can. I just bought a '91 n/a a week ago and it has started just fine for me everytime until today. I've been keeping it at my shop until the midwest snow storm this weekend was cleared up, but I went to get it out today and it just cranks but doesn't start. On Saturday, I moved it from one bay to the other, so it only ran for a few minutes.

I smell fuel when I start it, but it doesn't seem to be creating any combustion. I pulled the plugs and blew them out with air, cranked the motor with no plugs in it, and reinstalled the plugs. The problem still exists. Anyone have ideas?
