Had same problem. It's the "float" couple yrs ago. No gas allowed after the prime burns up. IF I REMEMBER--there is a small screw in bottom of the float tank--it has to be unscrewed and then put back in. Think it trapped some sediment or ??? Very easy to try
Have a cratfsman (briggs/Stratton) mower. Carb destroyed twice on first mow because no stabilizer used. Can I switch the carb to one that doesn't need stabilizer? How would carb be identified to know difference?
thanks
