i have a 96 that I have had a love/hate relationship for about three years now. Always fought to get it lit. Took it down yesterday and started over. All the simple things: checked rubber gasket on filler cap, made sure the lead seal was good for the burner, flushed the tank a couple of times and oiled the leather washer. NRV seemed to be working so didn’t mess with it but cleaned the mesh screen. All things I have done before It pressure tested fine. I have since fired it up numerous times and it ran like a champ each time. The proof test-run was a pile of heart stopping bacon. Ya ho! In celebration I paid my subscription to CCS which was long overdue from all the info I have mined out of here. Now I trust it, the search is on for a decent tin as it is an orphan.
