I have a 1991 Honda fourtrax 300 2wd. Starter hasn’t worked in 10 years atleast. Always kick started it. It sat for 6 years untouched, then I put fresh gas in it and a new air filter and it fired up and I drove it once. The rear end is completely out of it so I didn’t drive it long before I parked it for the last 2 years. Now I have cleaned the tank, fresh gas, cleaned the carb 4 times, each time I got it more cleaner then the time before. When kick starting it would fire and run just a second and die. Done that for days. Now all of a sudden its not even trying to start. Spark is confirmed, line from tank to carb is clear and flowing good. Now when I pull the carb, the engine itself smells like old gas bad, like no fresh gas is getting though the carb. On top of the carb it has a round rubber plunger thing that doesnt seem bad, but i really dont know for sure. On the overflow drain valve, it leaks gas out when rocking the fourwheeler and at just random times like theres no vaccum or something. Sorry about the long story. Any help would be great. Thanks in advance

Also want to know, the knob that adjusts the throttle, I played with it not really knowing what it did until I had the carb apart, now I need to get it set to where It should be. does anyone know what to set it at? Also the primer on the side of the carb does have a tiny needle pinhole in the rubber boot that sprays a tiny quirt of fuel every push.
