bought a used 2000 350 wolverine only run at idle or so no slide movement at all. tore down carb and cleaned everything reset float pilot jet stopped up cleaned out put back together no start no fire at spark plug no fire at plug wire. fixed carb slide and pilot jet set screw two turns out but no fire. when i started it would crank up just not run now nothing no fire the only thing i can think of is we probably left the engine on offf switch on but still had the key swithch off. dont know where to start and it doesnt make much sense either maybe someone here can help direct me as to where to start?
