will look around for a few more days locally but so far no luck when i pulled one of the 850s down still had the paper gasket had not had the upgrade fitted and the leak had lead to visible scoring on the piston and a carbon deposit in the exhaust port. I have found a couple of old saws that have the upgrade kit which is a piece of spring steel that puts pressure on the pump in these 1 bolt pumps so would like to get a couple or so of the later rubber style gasket
