Got this great condition KeroPet. A real survivor in top condition all-round. Got ifbfor half the asking price too. Barely used I assume, the spirit cup hasn’t even tarnished. Quick fettle of the filler cap seal, freeing up the valve and pricker and test burn on the bare burner seems spot on. Freed up the NRV but will need a clean and pip. I’ll follow the removal advice of @Darryl Durdin , however forgot ask do they have a lead washer? Do they go back in ok without any tricks? Thanks all.
