I have an 05 John Deere L100, about a year and a half ago it stop turning over. I just adjusted the valves after the 1.5 years of it sitting up. After the valve adjustment it turns over fine, but now it will not start. There is no gas getting to the carb and there is not even gas getting to the filter between the fuel pump and gas tank. Ive replaced the fuel pump and made sure all line were clear and cleaned out the carb ( im no carb expert ) but i removed the bowl and cleaned the ports going down to it and made sure the float was moving. What am i missing? Or any other suggestions?
