The saw loads up like too much fuel when idling?

This may be a carb issue, leaning it off on the L screw should realy sort this out, if not then it could be the needle in the carb leaking, but this would effect the high revs as well, make sure the air filter is clear as this will richen the mixture, partly blocked exhaust port, or muffler will also richen the mixture, 65psi is not very high, check the condition of the piston through the exhaust port. Older saws ran on a 25.1 fuel oil mix
