Only runs on starting fluid being sprayed thru air cleaner. Pun is good. New fuel. Great fire .
Sounds like a fuel system problem. My favorite lawnmower cleaner is e85. Go get a half gallon of it and some colored 2 cycle oil. Replace fuel system fuel with e85 mix and remove carb bowl drain screw or entire bowl. Catch escaping fuel and clean up the bowl if totally removed. Put carb back together when fuel changes color. Drain remaining e85 and use for cleaner or in your flex fuel vehicle.
