Parts For ST .35 Stunt Engine
We're sorry, but your engine has been out of production for so long that we'd no longer have the parts for it.
You can make a rear cover gasket out of almost any kind of material. Thick vellum will work. We've even used white card stock in a pinch. It's really not critical. It just needs to close off air leaks. You can also buy some fiber gasket material from an auto supply shop, which will also work nicely.
