revving my briggs 2 hp .. from idle i just throttle it to max (not connected to anything except #35 centrifugal clutch) it just bogs down probably cause i gassed it too fast. now i cant start it at all. valves are good piston good sparks, LOTS of compression, carb cleaner cant get it started either. pouring some carb cleaner into the spark plug hole helps some, but then it just does like 1 cycle and dies. took carb off, sprayed alot of carb cleaner into it. didnt work. took out the air mixture screw, cleaned it even it was new. going to buy a new carb, but b4 that any suggestions what happened?
