"Very important on Detroit two strokes as a few cylinders will really breath when sitting. A little block heat on the DD's solves the liner corrosion issue."

Our solution was to replace the gaskets on the air box covers , to make removal/replacement a 5 min job.

Spraying fogging fluid into each cylinder bore , a spin with the starter and respray the cylinders where the piston was in the way works here for soggy FL summer layup.

All that fogging fluid makes a bunch of smoke on engine restart after 6 months , but there is no white smoke on following startups , so the cylinders have not rusted.

The dry stack exhaust is sealed , and the blower intake also gets covered .

Nothing will stop changes in air pressure from the engine , but at least there is no breeze thru it.

Summer layup is as important as winter layup, 6 months of non use is not what DD's were built for.
 
FF- By sealing stack, covering blower suction and fogging airbox you should have no problem with rusting liners. Kudos.

For over 6 months there is still the DD problem of sticking injectors.

Da Book (WWII training manual) sez to use "turbine oil", probably easy to get then.

I simply spray the injector plunger with PB Blaster and check very carefully at the end of any layup.
