As I mentioned, make sure the pump arm has full travel and is not binding, as it does compress a bit as it slides over the cam lobe.
If it was on that engine and working properly until removed, what has changed? It is quite likely something in the pump if it was apart...
Just trying to use some logic here, and I do understand the illogic of old Brit cars...

: still struggling with it...
: Maybe today. Someone on another forum
: suggested tying a string to the lever
: to hold it up and yank it out before it
: is completely seated. That's been
: working, sorta, but the pump keeps
: binding on the studs.
: Maybe I can get it to behave today.

: Your understanding of the procedure is
: correct, it's fairly straightforward.
: A couple thoughts-
: After the lever is fitted up on the cam
: lobe, and you push the pump body home,
: there will be a little resistance as
: the arm is pushed up slightly.
: Make sure nothing was displaced during
: the top R&R, that could be binding up
: the action. If you had the diaphragm
: out, the end of the shaft fits into a
: slotted link and it's a bit fussy to
: get fit, it could be causing a bind.
: In any case now would be the time to
: check the pump before you fit it, just
: to make sure all is OK with it.
: Keep us posted!

: it's giving me fits.
: The book says to have the pump lever on

: to get the lever on top, even with the
: lobe downward and holding the prime arm
: so the lever is up. Any tricks or
: something obvious I am missing?

: If the pump was working properly, and
: just leaking fuel at the fitting, the
: cam lobe didn't just wear out.
: You might also make sure the check
: valves in the replacement are in good
: shape. A lot of pump issues are caused
: by leaking or displaced check valves.

: Good ideas, both.
:
: lever should be fine. The lower portion
: of the pump (arm included) is the one I
: ran for 2 years on. I only swapped the
: upper portion, and it worked the before
: I pulled the pump off...
: Worth checking though. I never thought
: of looking at the lobe on the cam. I'm
: not entirely sure how many miles my car
: has on it, so I may as well have a
: look.

: The first thing I would check is make
: sure that the replacement pump is the
: same and not the later style with the
: long arm & spacer.

: Been a while since I asked anything
: here,
: so I'll let you have the first crack at
: it since it will be a day or so before
: I can act on the advice:
: I got my engine started for the first
: time in years. (YAY!) The problem is,
: last time I messed with it I must have
: cross threaded the outlet of the fuel
: pump. (stock glass domed mechanical
: one), so after dealing with a leaking
: pump for the first test firing I
: replaced the now bad part with a spare.
: Hindsight tells me I could have done
: this without removing it,
: but....Anyway, now the priming lever
: works but the engine seems to run till
: the carb bowls run out of fuel, so it
: sounds to me like I didn't get the pump
: seated correctly. Any ideas on properly
: seating the lever?
:
: Just for kicks, here is it running.
