Very nice find! The original twins of this type are pretty smooth reliable power units. Congrats!

   Thank you dieselgman. That means everything coming from you. Do you carry spares for this engine?
Are 6/1 parts compatible with the 12/2?  Parts  like valves and guides, piston rings , valve spring retainers and springs, and most importantly a starter HANDLE. They actually could not find it.. Thanks.

Hi, we still have substantial parts stocks for these... the majority of the 6/1 parts will service a twin 12/2. We have not dealt directly with the Field Marshall brand, but yours most likely will conform to the Lister designs. No more twin engines remain in our USA stocks, but we do have quite a few singles available here.  dieselgman gsj@gci.net

Update the dieselgen email address to gsj@gci.net please.

The dieselgen address has not been accessible for a considerable time and we do not anticipate recovering it at this point.

Butch is right... there will be no advantage nor reason to use an umbrella type valve stem seal. That design is only valid for a fully enclosed valve cover environment with a large amount of suspended oil mist/splash. Your Lister requires a small amount of oil to lubricate the valve guides/valve stems and that is supplied via a tiny amount of splash off the valve springs drawing on the oil you manually place there in the valve spring reservoir every 8 hours of operation (or thereabouts). Also, avoid the drilled valve guide mod as Butch has also indicated.

Yes, it sounds like you are doing it right.

We have moved these around a lot of differing ways... Best one I've seen as used by some very clever Amish folk - steel bolt-on lifting eyes on each cylinder block.

Basically, keeping the center of gravity below your lifting point is the key requirement. No fun having one tip over!

The air ducting in Lister/Petter sound enclosures simply provide a serpentine path for the cooling air to flow through, along with foam dampening on all surfaces. This keeps noise dampened as well while providing an open air pathway.

Tag stamping seems erroneous... Please post overall engine picture. We know all Lister types and can help identify.

Heated sodium hydroxide (180 degrees F) in water is best for stripping cast iron hot-tank style. Not recommended for aluminum alloy, but there are also buffered versions on the market for that application as well.
We often leave the original red primer in place after all other paint and contamination has been released and rinsed from parts.

ST2 Lister camshaft is retained by thrust bushings at front gear cover and engine block. Remove gear cover and you will see the cam gear. Remove governor assembly, withdraw fuel pumps and tappets, remove oil pump (out of bottom of block), remove pushrods and withdraw their tappets to top of bores... (best done with engine block laid on side). Cam will withdraw out front of engine. Check if fuel lift pump tappet is installed - remove if it is there.
