I bought a 1949 77 RC that had been sitting out for a few years in south Georgia. Motor was not stuck, but the carb (TSX363) was a mess inside the bowl. I got it cleaned out, chased all the jets, and put in a new kit. 

The machine has a new wiring harness, plugs, plug wires, points, condenser, rotor, cap, battery, coil, and starter. The fuel in the tank and bowl is clean. I get a few puffs of smoke when I try to crank it, but it just will not turn over. There is fuel in the carb and the engine turns real free by hand.

I set the idle mix and power jet by the book (backed out one turn after lightly seating). I have the governor control set in the middle of the quadrant, and the choke is working. I am at a loss. Any ideas would be appreciated on why I can't get the beast to fire up.

Thanks.
