Toss the WD-40 for this application. Get an actual lubricant (liquid wrench has a can of sprayable oil)
(I have nothing against WD, but it ain't worth squat as a long term lube.).
WD-40 will not be the long term fix.
Hoping to get by with just some WD-40 and until the spring when I can take it apart and do a good cleaning.
I will be using anti-seize as noted in the service manual. I already have some because I bought a tube for the combustion air fan set screw on my pellet stove among other things.
