Carb treat

I have two M's - one of them gets used about daily. In all of
that I have never had to take a carb off. That back nut is a
special treat! I'm about to just pull the manifold and get it over
with. It's either that, or I am going to re-work a 9/16 wrench for
the task.
 
rework the wrench, its not all that bad.
pulling the cab off of a ford diesel 1 ton, to do a gasket on engine, now thats crazy.
 
I'm pretty sure Ferd had a department to design things to be difficult. The whole front end had to come off of one of my buses to put on an exhaust manifold. That wasn't expensive or anything.
 
You need one of these... I believe the term is "obstruction wrench". Mine is a "PROTO", but looks just like the one in this photo (found on the "net).

Here's a couple possibilities. I made the top one to remove the pump bolts on those junk GM diesels they were putting in cars and trucks 40 years ago, it works good on an M manifold.

I use a standard, run of the mill, Snap-On stubby combination wrench. Put it on the nut so that the wrench angles up, not down. I've got another "generic" made in China 9/16" with very similar dimensions. Both wrenches work equally well.
 
Yeah I have a whole drawer full of wrenchs I have had to modify over the years for distributors, carbs, manifolds, engine to transmission, etc.
