B&S 20 hp hard starting cold
I have an Intek v twin 406777-0151E1 about 14 years old. Compression checks at 130-135, valves adjusted yearly as required. Uses very little oil. Fuel pump volume appears good, spark good. The usual starting procedure is choke on full, throttle full open, crank for 10-15 seconds continuous, bursts do no good. I took the fuel line from carb to fuel pump loose at the fuel pump, propped it up in air, filled it with gas, and several hours later the gas had disappeared. Was thinking leaking needle valve or carb solenoid valve causing this. Just purchased this mower a year ago, and have no idea if carb has ever been worked on. Any ideas?
