Hi mate, the mower from my post is still running great with no over revving or melting. Disconnect the governor hose and blow through it to check the nozzle isn't blocked. If ok, disconnect the hose at the nozzle, with the engine running suck on the hose and confirm it brings the revs down. If ok, replace both inlet manifold and starter orings. If no change remove and inspect the governor diaphragm. It's the over revving that causes the excessive heat and melting.
