Lead paste valve stem assembly lube/anti-seize Armite 250 Briggs 93963 X

[farmall]

While hunting old Briggs and Stratton info I found something I'd missed all these years, lead past anti-seize which Briggs and many others used for valve stem assembly lube (and machinists use and sometimes still do on lathe centers because they're so highly loaded during cuts). I bought a can to play with and it's like any other thick anti-seize in texture. In ancient times it was standard practice (so standard nobody among my ancient bros ever mentioned it like most other "assumed" techniques) to use this building any engine as lead makes such a nice lubricant due to its "cushioning" effect under shock loads (one reason TEL was added to fuel to protect valve seats by depositing an ablative cushion of lead oxide during combustion).

Still available for industry but superseded by Briggs because idiots lick their fingers, it's dandy for stored overhauled parts vs conventional assembly lube and in various forms beloved by ancient machinists for use with dead centers (not our problem but worth noting) and as a general low-speed high load bushing lube:

which is also (old parent company) as I confirmed with some looking

and in its modern labelling https://armitelabs.com/product/lp-250/

It will make dandy assembly lube for valve stems and similarly loaded parts on the hot-running air-cooled engines I molest.

Wear disposable gloves as lead really is impressively toxic (my bros wife had to get chelation therapy because her dumbass father cast bullets indoors when she was a child) but that kind of contamination is nothing like that from lead paste unless you do as artists used to and lick the tip of your brush when painting with (still available because it's awesome) white lead pigment.

Apparently gunners use LP 250 too and of course a bit of lead is no problem in that use. Here's some overpriced repack LP 250 but it would be silly to buy that little for that much. https://www.jprifles.com/buy.php?item=LP-250

ETA: The #609 looks like some handy stuff to have around.

250 works for that too and was/is used on tappets. There's lots of overlap.
