After cleaning my carb and changing all the gaskets (2) and O'ring, went to start it (this is a prime to start carb, no adjustments). After I primed the carb, I tried to start it, didn' even sound like it was trying to start...removed spark plug, it was dry, didn't even smell like fuel, next I removed the air cleaner and checked for fuel in the carb next to the butterfly, it also was dry...this is hard to believe, because when I cleaned it, I used carb cleaner and blew it out with an air compressor, everything was clear no blockage, Next I checked the suction on the line leading to the air cleaner, it had good suction. I then removed the fuel filter bowl (full of fuel) removed the float and the needle valve they looke good...Thought I would just try to see what happens if I was to put it back together and leave the needle valve out (since it is a straight shot to the carb), left needle valve out , primed carb, tried to start, started on third pull. Installed needle valve nothing. "Any suggestions would be grealtly appreciated"
