No need the seal the engines, I think you are just encountering carburetor setting problems, if the engine runs too hot, you are too lean.

Maybe your idle is just too low.

If the engines rpm stays high after a high speed run and lowers after a while then the LHS is too rich. Lean it out more and when after the idle stays high, then just lower it by unscrewing the airscrew.
