First ride of the season I noticed a squeak/squeal coming from the top end of the rear cylinder. It sounded like something going bad with the cam shaft. The engine was running just fine, but there was a bit more popping on deceleration (a clue). It turned out to be the air valve that supplies fresh air to the reed valve. It is located directly above the rear cylinder under the seat. It appears that the vacuum valve diaphragm has failed and is now producing noise. I blocked the vacuum line for now (noise is gone) and will marble or coaster when I get the parts.
