I fully understand this is a 4 mix engine and not a 2 stroke, but I restored a 1980's vintage echo SRM-2200 and just so happend to score a NOS seal and gasket kit from ebay. Not only that, but the seals are still avail.
I have a lot of vintage 2 stroke OPE, and a vintage 2 stroke motorcycles that seals are NOT avail anymore. Before my selas do what these in the video did, is there any additives to preserve them?
