Thanks. I'll check the float & needle. The needle did fall out while I was replacing the gasket, but I didn't make any other adjustments when I opened the carb.
I had checked through everything I could think of on the spark side of the equation and everything seems to be working as it should. That's when I moved over to the carb.
The carb is clean, I'm getting fuel when I move the accelerator arm, and the choke opens and closes properly.
