Pull the air filter off & start using the fluid
Keep on shooting short I said SHORT shots into the carb
If you can keep it running for a minute or more that confirms a fuel problem
IF you confirm a fuel problem then remove the fuel line at the carburettor and crank the engine
You should get a strong pulsed flow the full diameter of the fuel line, not a feeble dribble or drips .
Naturally no smoking etc and use some sort of a catch can
If the fuel flow checks out good that only leaves the carburettor and in particular the carb solenoid as the wires could have fallen out of the plug or have shifted & now melted etc etc
If you can not keep the engine running then remove the rocker covers and pull the pushrods out to check they have not bent or even jumped off the rockers .
Let us know how these tests go for more instructions
