Rocker Cover Gasket

I disassembled the engine. made a list of parts. I looked up the torque values online and using the new parts reassembled the engine. It fired right off and ran smooth. The parts I received from Replacement parts fit perfectly and the price was right. They were delivered in a timely manner.

Check rocker arm movement to determine cam condition.
Replace worn out cam (one lobe gone).
Good time to change the seal at this time too.
Carefully adjust the valves "by the book".
Check / clean carburetor very carefully. The idle jets are very small and clogs aren't easily seen.
(took 2 attempts)
Turns over freely now and runs like a top.
