Hi if you have got it cranking remove the plug and check for a spark the plug must be earthed to do this if you have a spark it must be fuel pore a small amount in top of carb make sure ign is switch on hope this helps.Ron.
Spark and gas??? Must have both. Pull spark plug wire and check for spark. If you have spark, check gap on spark plug. Check the bowl on carburetor. loosen bowl screw to see if gas is coming out. If you have gas coming out, carb needs to be taken off and cleaned or rebuilt.
Clean or change air filter. Clean, gap or change spark plug. Empty gas tank add fresh gas with Stabil. When spark plug is removed pull rope several times to blow out cylinder. Spray starter fluid in spark plug hole before replacing spark plug. Clean outside of carb so choke works freely. Spray starter fluid into carb breather hole with air filter removed and try to start. if running replace air filter and cover. If no start disassemble carb and clean. If no start replace carb.
You can try buy a new spark plug and replace it with the old one. I had the same problem! You just have to keep pulling until it catches! Or maybe it's the carburetor that needs to be replaced! I had the same problem wih my scooter. I just changed the carburetor and it worked fine :)
Probably dead gas from sitting too long. Dump it out & put in fresh gas.Could have moisture in it. Pull out spark plug & crank it over several times after putting gas & let it sit a while to dry out or blow it out with compressed air. It should go.
