First check the hose as was stated above. Take a good look at the O rings on each end too.
Next, check the fuel pump, Disconnect the line from the carb and pull the cord, it should pump fuel out way faster than you think it has to. (create pressure on carb needle valve). Pump is on R side, follow the fuel line from the carb back.
Remove the spark plugs and ground them against the block, pull the cord, you should see a bright blue spark, if the spark looks weak but is still there, it's probably the coils or points.
To check the points there should be an inspection port (hole) in the flywheel that if you rotate the wheel slowly will allow access to the points. Check for proper gap and excessive wear or burning of the contacts. Points can usally be replaced without removing the flywheel. Use a magnetic screw driver so you don't drop any screws. If you drop a screw, you'll have to pull the flywheel to get it back. Still not a bright blue spark? Coils are next.
To remove the coil, you need to have a wheel puller to remove the flywheel. I have beat them off with a hammer and block of wood, but that was a field emergency. After the wheel is pulled you'll see the coils, They are easy out, easy in.
While you have the flywheel off clean it out good and slightly polish the flywheel contacts with emery cloth to remove any film of rust. Wipe clean and reassemble.
Still won't run well? Take it up to Lee's in Hyrum, tell him what you've already done and see what he can do for you.
