I would pull the m/c then adjust the rod so it is just touching the plunger, Not pushing on it when m/c is in place. That would give you a good starting point or even work. That's how I do the one that belongs on there and seems to work for me

This isn't your problem, But you normally bleed from furthest wheel first

I would not use a torch in that area, Gaskets, Fuel line, Etc there. Buy a new one first so you know what your dealing with. You can maybe put a hacksaw blade in hole and make a small slit, Then buy a very small chisel and maybe get it to fold in on itself. I would pull expansion tank and you should...

What brand engine paint is everyone using for their 66? I see Pat Wilson is selling Spruce good for about 250 Degrees . Don't seem to see the old corporate blue around. I have a can of dupli color Ford dark blue and that's good for about 500 degrees, But think its a later Ford color.

It may be difficult to make out colors in photos since many wires are tracer colors. A better bet may be the service manual and Top manual. They have schematics with wires numbered to indicate colors

Going by the length of connectors on back I would say that is the 66 amp meter. Earlier one has longer connectors on back so the insulator has room to slide over them and then the heavy wires put on with nuts. Here is a pic of both. Early one on left 66 on right. anyone could jump in if i'm not corr...

Thanks for the correction Bob! Learn something here often!

No horn relay make sure your horns are grounded and put juice to them and see if they work. You can have someone press horn button and test wire for voltage

Just for the heck of it while working on cars checked three pulleys. 66 w/o a/c single pulley much larger diameter has no holes...64 with 66 motor and a/c no holes...Double sheave pulley on bench C5AE-A no holes.
