Started in 1975 and 2005, run for 15 minutes maybe each. In December 2019, I changed out oil, rattled some gravel in gas tank, shined magnets, set point at a matchbook.
Started it, got it to run smooth at full choke, idle for 1/2 hour, then died. Then it ran sporadically for couple minutes, then starved for gas. The needle valve seat had corrosion fuzz, I shined needle and cleaned out needle shaft. Filled oil bath filter to appropriate level.
Have run at one setting for a hour, one setting 1/2 hour and 3 - 10 minute runs, all on different days. Governor adjustment is operating proper. Does not leak gas while running, but when I shut down using the kill button, a quantity of gas dribbles out bottom of carb. Then it has a slow drip, until valve is shut off at tank.
