There is a drain plug in the bottom on carb. When it stops, see if there is gas in the carb by removing the plug.
If you installed an in line filter, mistake, they vapor lock when fuel gets to 135, which doesn"t take much, heat from radiator, muffler and engine.
There are 3 screen filters, one on top of the sediment bowl, one inside the sediment bowl and one at the right angle brass fitting where the gas line connects to the carb. The inside of my thank began to flake off and would choke screens.
Electrical problems may act like fuel problems too.
