G21A will not run!
 

I am new here so thanks for this place. My problem is my G21a gas just quit starting. Well, it will try to start if I just barely press on the gas and I can run it up and down the driveway this way....sometimes. But if I press the gas down it will die and may not start for a while. I have good compression, good spark and a clean air filter. Have fuel pumping out the line at the carb. Any suggestions?

I am suspecting the carb is gunked up but I sprayed it with cleaner. A valve stuck maybe...but I doubt it would run at all with that. HELP!!!

I would start digging deeper into the carb. I'm wondering if the main jet/high speed system is clogged. Then again if it were me, I would be changing vacuum hoses to the fuel pump as well as fuel filter and fuel lines from the tank to the carb.
