Have you cleaned the carburator ? It seems the main jet has some kind of obstruction.
Try cleaning the carburator and well a tune up would be fine too after the clean , check the plug/s & air filter too.

By spraying it you may have inadvertently blown dirt or grime even further into the carb. It doesn't take much to cause the float to stick open. This would result in a constant flow of fuel into the bowl. Once filled it will escape via the overflow.
The best way to clean the carb is to remove it from the motor, disassemble it and clean it using a small brush. If you have never done this before just take you time and make sure you have a clean work space to do this in. There are really very few parts to this type of carburetor and once you have done it a couple time you can take it apart clean it and have it back on in under an hour.
Hope this helps.

Turn the adjusting screw all the way in until it LIGHTLY seats. Now back it out one and one half turns. Do the same adjustment for the throttle screw on the right side of the carb. You are now back to the stock factory settings.
Could you take a moment and rate my answer? Thanks!
