Hi All,
I have an interesting situation I am currently involved with breathing life into a H36 Dimona (prev VH-GNW) in New Zealand. I also have what remains of VH-WVW which I am using as a spare parts source. The engine that was installed in GNW was a L2000 and a standard configuration .. Ie a Slick mag and used the non shielded plugs marked as Limbach LB-N41.0. The thread length the same as the shielded plugs I currently use for the other Limbach powered TMG's I look after. The L2000 from VH-WVW was fitted with a secondary electronic ignition system .. 2 plugs per pot. Removing the plugs from this engine , the thread length was a lot longer and marked Limbach LB-L41.0 I am a bit anal about plugs and ensure the installed torque is as per the Limbach data to avoid head thread damage. However the long reach plugs are a real problem because of the number of threads exposed to combustion damage. Removing the plugs and pulling damaged threads thru the head is a quick way to destroy the thread integrity Both top and bottom plugs were the long reach ones. I would be interested in any comments.
