Yardman 3.5 HP Edger (256-599-401) - Won't Start

I have a Yardman 3.5 HP Edger (256-599-401) that won't start. I have confirmed that I have spark as the engine will fire briefly if you spray a little starting fluid in the carb. I have also replaced the sparkplug to no avail... I have confirmed that I am getting gas to the carb from the tank. I removed the bowl from the bottom of the carb and sprayed the heck out of the carb (inside and out).

I suspect that the carb needs further attention (rebuilt because of varnish?), but I could use a little guidance to confirm my suspicion and how to proceed. I am reasonably mechanically inclined but I have never rebuilt a carb.

careful what you use to spray it out with. Carb cleaner will play havoc with the rubber parts of a carb like bowl gasket, needle seat, etc.
that low speed circuit screw on the side that 30yr is talking about can easily be damaged if overtightened. lightly seat it then back it out 1 1/2 as 30yr noted.
