its new gas 40:1 ratio, my cousin actually helped me today get it started, we had it hooked up to the hose seemed fine when you feather the throttle but when u start on it it bogs out, doesnt shut off but it will bog out then rev back up. and when i had it in the water last week it was just moving really slow with the throttle punched, my cousin thinks its possibly the fuel pump because it has been sitting for abuot a yr without being run.
