This is a bit of a stretch Roland but worth noting I guess. I worked on
one of those this summer with the same problems at similar hours.
Eventually discovered the accelerator pump on the carb had the diaghrams
completely desintegrated.
Here is the big stretch. Under the valve cover on one side the rocker arm
assembly had come completely apart. Put that all back together and instantly
had compression that was weak before. Go figure.
