Nice work as always. The Amish are renowned for their carpentry not their engineering skills. I`ve often wondered why Lister didn`t specify a Gibb key with a bit more meat in the head. Will you be replacing the Gibb keys with Indian copies? The last set I ordered had the wrong taper and had to be filed to fit, they also don`t have the milled slot down the middle.

I`ve had trouble posting pics in the past, check the camera resolution, if the file is too big it will get rejected.

On to stuck flwheels.
Spray some snake oils on if it makes you feel good but 19 years later they will still be stuck.  12 tons pulling and couple solid whacks on the back side and this one moved, NOW spray some snake oil and it will do some good.  Often times heat is needed but not on this one. Photo won't pass security for unknown reasons so imagination is required

Lister VA in the shop with typical ex Amish owned problems includinging both Gibb keys having the heads broken off. At least they quit this time instead of ruining the flywheels.

A far as my research got, this starter fuse is needed due to LOW compression - large TDC clearance - and therefore air did not reach high temp in order to make combustion.

So the fuse autoingnites with compression and stays lit till it burn completely.

As you can see the TDC claearence is about 4mm and must add prechamber volume (see here: https://listerengine.com/smf/index.php?topic=9555.msg111218#msg111218).

my 12/2 stay at 1,3mm - https://listerengine.com/smf/index.php?topic=8320.msg102670#msg102670.

My 5cents.

Hi Cobbadog, a lot of older diesel engines used these for first ignition of diesel. These engines did not have electric starter motors and the compression required for spontaneous combustion was too high for hand cranking.  These are basically a fuse, you light them and put them in a small chamber attached to the combustion chamber where they initiate first smoke at a lower compression. I wish I had been on the forum more recently, I could have saved VP some money: a piece of lit cigarette will usually do the same job. Cheaper and locally available, don`t recommend smoking them!
