Let me guess…
A. you hardly use the kicker.
B. you did not or dont ever drain the carb or run the carb dry after last season and seasons before.
I hear this from so many guys,
If you only use the motor a few times a year you need to drain/ ru the carb dry by disconnecting the fuel.
Also you MUST drain/ run it dry prior to storage. Stabil, seafoam and such are all jokes. There is no substitute for doing things proper. The jets in carbs are like arteries in our bodies, they get plugged, espicially when gas sits in them, as it dries/ evaporates it leves behing a film and over time it adds up. My guess, if you havent ever drained/dried the system before storage u need to have the carbs cleaned. start buy putting a bit (1 oz.) of gas directly in the barrel of the carb, bet it fires… means no gas is getting in to the cyl.
There are basically only 3 things that cause engines to not run
1. Ignition
2. fuel
3. compression
that is the order in which to systematically diagnose engine failure
