M-1 Intake Manifold

Here’s the one I reworked with epoxy. I first straightened the sides of the carb base opening so that there would be one continuous piece of epoxy (instead of the two slivers on the secondary side along with the piece for the primary side) I also drilled a series of holes in the perimeter and drove in thin alloy round stock as “pins” as well as dimpled the surface for better grip so that there would be no way the epoxy could ever break off and be ingested. Haven’t gotten around to trying it out yet.

I’ve done it without the dowel pins…

I broke off one of the 4 moon slices. I shut down immediately and by total luck the pushrod popped out clean when it hung open a valve.

took it off, checked everything, re-lapped valve. Remove ALL the epoxy work….been that way for years.

Would like to get it welded.
