How are the valves adjusted in the SOHC? 50k sounds a little early but I hear a distinct valve rattle under load/acceleration at 2800 to 3000 RPMs. Also in the cold morning the engine will only idle for 2-3 seconds before dying. Have to keep foot on the gas to keep it idle when it does this. Also when starting I can sometimes hear that same rattle described above for a brief instant.
Valves out of adjustment?
How are they adjusted? Are they those little replaceable cam discs that the cam lobs depress to open the valve?
