#1 reason for non starting
#1 reason for non starting is fuel
#1 reason is bad gas
#2 reason is water in the gas
#3 reason is old gas
#4 is holes, ports, in the carb are clogged or partially clogged
#5 fuel is not getting to the intake valve, fuel is either not getting to the fuel bowl which means line, petcock, or fuel inlet valve is sticking; or not being pulled up through the main jet located in the middle of the carb underneath inside the fuel bowl.
When I have a starting issue, I loosen the nut on the fuel bowl and drain a little gas in a clear soda bottle. If there is water in the gas, it will sink to the bottom. Then look at the bottle, you will see the separation between water and gas! You can also see if the gas is not clear, there should be virtually no color to it, then drain everything! Everything! Your gas can TOO, in to a clear soda bottle. Completely! Until the can is totally dry. You brought the problem to me. I'm going to solve it, my way. I don't believe you.
Other than very very seldom reasons for non starting such as seizing engine, very low compression, valve lash, valves not sealing
Only two reasons, ignition or fuel
Spray starting fuel in the carb or in the spark plug hole, if it starts, generally, it's not ignition, it's a gasoline problem.
