If it starts at WOT, I would assume it's a bit flooded. If so, it's not going to immediately go zooooom - booooom! It'll flutter around as it clears itself out.
You can also pull the throttle cables out of the top of the carb a bit. The cable can be pulled out of the brass adjuster and propped on the edge of the adjuster to give you some throttle. Then if / when it fires, you can just bump the cable and it'll drop right back in. Can be a pain without an electric starter or a helper. Been there...

I'll try that tomorrow. Oddly enough, I held the throttle about 1/4 open on some pulls trying everything I could think of after work today, but it didn't seem to help. How quickly can you back off of the revs once it fires at wide open throttle?
