7 - Rocker train;

8 - Injector and fuse holder;

9 - Governor controller and decompression lever;

10 - Fuel filter assembly.

Almost done...

So close now and looking good too.

Fine tweaks at the German. I got to fill with brazing the decompression lever in order to make it accurate with intake rod stop nut.

And a tour to scrap man with some junk, found there a kerosene torch to restore. Nice isn't it?

A few pic to the show.

Belive, its the same torch! 1st clean is done. Got to put new rubber gaskets, and leather in pump.

Decompressor lever got paint... again.

Nice repair on the lever. Lovely clean up on the blow torch. My Dad had a couple of them when he use to use them for heating his soldering iron. Unfortunately when he move to come live up here he tossed it out.

I too have a couple of those from my dad who was a council electrician in the early 50's.  I also have his original pricker for cleaning the jet, which blocked often.  He told me they were used mainly for making leaded joints (before the days of resin joints) using a grease cloth.  2nd most important job was for boiling a kettle to make tea.  I also have a cast iron contraption that hooks onto the torch for the purpose of supporting the crucible or kettle.

Gentles,

As long as I cant get an original fuel tank, that holds return fuel lines, from IP and injector, ill put them to return to fuel filter - off course with goose neck, with lines passing by top level of fuel tank - and therefore fabricated a banjo tower.

PS: already waiting for the zundfix to fire it!

[cobbadog]

Lovely job there VP and neat too. I was going to say that it is not hard to fit some copper tubes into the tank as a return line inlet but your idea works just as well.

[sirpedrosa]

Hi Gentles

YUPI! The zündfix arrived from Germany.

Buy it from https://www.oldtimer-kuepper.de, and Im very happy with deal.

They are reliable! They also sent a catalog.

Now got to put oil in, torque flys, and - again - put diesel on the seringe to give it the first run.

A few pics for the show.

Hi VP, what do the Zundfix do?Are they for starting the engine?

[ajaffa1]

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!

Ok, Some Lanz Bulldog and Field Marshall tractors use a similar ideaa for a cartridge start. There is a clip around the place on how to make your own using blotting paper and a solution with I think salt petter in it. They roll them up like a cigarette and put them in a combustion chamber then hit a shot gun type of cartgridge with gunpowder only and that kicks them off.

Cobba, Bob and Gentles

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.

The German got his sump filled with fresh oil - 3,5L

Oil pump squirts ok - I think it should have a pressure relief valve, but as far I can see it doesnt.

Next task: screw tight flys nuts.

Remove fuel line to IP, to make test runs. After all ok Ill put line again from fuel filter.

Some pics for the show.

Gentles,

Today, late afternoon, give flys a good squeeze with proper wrench ().

Got enthusiast and put also crank boss on, and pulley.

Syringe is on place too...

Almost there!

A few pics.
