Easy to rebuild
We have a Kenyon 2-burner in our H30. It hadn't been used in years when we bought the boat used. It is an easy and interesting winter project to disassemble, clean and rebuild the stove. Will take just a few hours. Usual wear parts are the pump leathers (now replaceable with inexpensive rubber U-cup), the filters, jets, and rubber gaskets. Don't forget clean fresh fuel. Purchased all of our parts at Fawcett's Marine Supply, Annapolis, MD at very reasonable cost. As stated in an earlier reply, flare-ups do go hand-in-hand with pressurized alcohol stoves, but precaution and common-sense will make it a joy to use. Ours now works great! Enjoy the coffee.
