2006 Yard Machines with 20hp Briggs intek single cylinder.
Quite while mowing and wouldn't restart. It had spark and was getting fuel to the carb. I removed the carb, disassembled and cleaned. Still wouldn't start. I removed the valve cover and found that the rocker arm stud on the exhaust valve had backed out of the head and the aluminum push rod for the intake valve was bent. i removed the head and cleaned the carbon from the piston and the valves. reassembled. i tightened the stud and replaced the push rod. I then set the valve lash to .004" for both intake and exhaust. i checked the compression and am getting 120psi. The mower then started and sounded good but when i put in in gear and started to drive it died and won't start. Any help would be great.
