99 Yamaha Breeze spark plug not getting wet

Hello all, recently changed out piston and rings per manual, put back together and cannot get it to start, spark plug isn't getting wet at all and fuel is being spit out the air intake side of carb. I set timing according to the manual and the lines on the cam sprocket and the flywheel exactly. Also adjusted the valves while I had it apart. Not sure what I am missing here as I have watched the valves open and close a hundred times now. Compression is a ton better than it was before the new rings. Pulled the carb the other day and went thru it completely, all clean. when I put my hand on the intake side of carb is will suck my hand in and push out, blowing gas all over it as well. Any suggestions? I have not sprayed ether into spark plug hole yet, but have verified plenty of spark. It just seems like my timing is off and cylinder will not suck gas into it. Any help is greatly appreciated!

sounds like the intake valve needs adjusting or is stuck. pretty much the only way you can get air out of the carb.
