The Aldrich Magnums and the K&B1L's are no good . If you send them all to me , I may be able to cover the postage .

AHEM .
The 1L you find mentioned in many a thing . Maybe in the ST 46 Era . So maybe a good 4-2 plug ? . Baffle Engines . more delecate .
The Aldrich being later , might be a schneurle plug . IF there is such a thing . Heavier Duty for the go hard or go home brigade .
Who's a lucky boy then !
The FIREBALL , turkeys manadged to wreck the CERAMIC insulator . Levering on it willo do that . Glow Connector or fitting the plug wire clip , on a B T/R .
What the hot tip was , was ARYLDITE & a Toothpick . You can guess the rest . But justin case - New or solvent cleaned , or both , a bead / fillet or High Temp. epoxy
( dunno if JB welds conductive . Wouldnt light if was ) Twixt post & body . So as to relive the porclain ? insulator of that task .
Uvawise , see ya dont go wrenching round on that little post their , old boy . Blue were the top B T/R plug , other than he pommy Taylor bespoke plugs .
