Carburetor rebuild
I acquired a second set of carburetors that looked to be stock 1965 for two
reasons - to have an extra set and also the ones in my car had been modified
and felt as though they were battling each other at highway speeds. The new set
were excessively gummed up but did not appear to have any corrosion inside.
Once I got them apart, I had Jack Dempsey take a look at them and he agreed
that they were in excellent condition.
I started off by spraying them with aerosol carburetor cleaner. Then I soaked
each one in a
Gunk carburetor and parts cleaner kit. That got most of the gunk and grime
off of them. The throttle shaft on one of the secondaries was still not quite
right so on only that one, we removed the shaft, cleaned it thoroughly and
then screwed it back in. One note if you do this: the screws are staked (also
called "peened" over" on the bottom so that they won't fall into the head
if by some chance they manage to loosen up. Make sure you tap the bottom side
of the throttle plate screws with a fine blade chisel if you have removed any.
Next, I started reassembling them. On Jack's recommendation, I put slightly
different needle seats in. I used 52's on the primaries and 50's on the
secondaries so they would run slightly richer.
Finally I installed them in the car and have been quite happy with the result.
If you are looking for a Uni-Syn gauge to synchronize your carburetors,
I found one for $19.95 from CB Performance
