And now I have to rebuild it all! All windings.

Take all coils from rotor, search for new ones (or someone who make them), counting turns, make a jig to wind new ones, etc, etc

Hi Gentles

Remember I had a restoration aside Lister 12/2 - a Penta 6A, 1971? And the dynastarter was refurbished? (see here: https://listerengine.com/smf/index.php?topic=8320.msg104124#msg104124)

After put it on the engine, all working good, dynastarter firing the engine nicely... after tuning idle rpm, and max rpm, it never started again with the dynastarter.

Tried another battery to see if the issue was from there.... and nothing. Thamn, maybe the dyna have some issue, I think.

All disassembled and... thamn, dynastarter is busted. Worst, rotor had windings destroid. Thamn!

Lesson learned: a few meters of nylon twine in the front copper coils had prevent the disaster. (Think was the full throttle that put centrifugal force in coils, and they just open to the side, and destroy all thing)

A few pics to show the disaster...

Hi Gentles

As far as I know that power factor is relatively to the magnetic and heat losses. Wont you all agree?

Hi Gentles

A few time ago I was told a very rusty iron still seated on a field.

Today I made a divert of... 200km to see it.

I think it looks worse than it is... off course its seized! I was told its seated under weather since my spotter remembers!

Couldn't make any better pics, because there was a shepherd dog warning me that was its place.

Anyway, ill try to fetch it.

Hi Gentles

My apologies to not share in last post some TLC to my latest acquisition, a Hilux 1992, that needed to tweak the injection pump (spill time was set a beat early, making it to sound a dry knock).

To pull out crank pulley I made some basic tools from "NASA's" plans, in order to reach the timing belt.

A few pics to enjoy...

Hi Chris

I think Cobba pin the point, and if you have a micro budget, dont jeopardize it. An HR (2, 3, 4 or 6) are direct injection and high RPM.

LEF members that uses WMO or WVO has low RPM engines Lister CS or listeroids, and thoes "fuels" need fine filtering, centrifuge to separate water, mixing to start and even heating to flow better.

Do you really need 10 KW? or 5 or 3 is sufficient?

Just a few cent to the rant!
