The engine would blow gas out the carburetor and the lock up, took off the valve cover and found the exhaust rocker arm split and intake push rod bent.

I replaced both rocker arms and intake and exhaust push rods. Adjusted the gap. I started the engine, it fired and I let it idle for a few minutes. The engine never sputtered or skip a beat. I mowed for two hours in the 8-inch high grass the riding mower pushed thru.

Thank you for your service, I will remember your company fo r future service.
