Trailmaster xrs 150 doesn't stary
I'm trying to repair the kart for my son. Fuel is going to carburetor and it will turn but won't start unless a spray cleaner or fuel into the carburetor filter intake. I completely disassembled and cleaned carburetor, added new fuel, changed plug which has spark. But won't stay on. I ran the fuel hose straight to filter intake and it starts up but won't stay on. Could it be bad fuel filter or fuel pump? I am going to try setting the ratio screws(little gold screws). How would one set the valves? Any help would be appreciated.
