<VV> 67 110/pg w/AC Timing, now Fuel Pump Kits

[Brown, David (San Jose)]

Joel's advice for starters is perfect-  Check the tightness, the screws
do loosen up occasionally, plus the pumps warp slightly over time.
Also, check your dipstick to make sure there is no gas smell.  If you do
need new gaskets the kits for our pumps ARE available, through:

They are $24.50ea (+ $7.50 shipping for 1 or more kits), so about 1/2
the price of a new pump (but maybe too expensive for our Corvair vendors
to carry?).  Plus that would give you the opportunity to check the
mating surfaces to be sure they are not warped (many are- most common
cause of failure these days), which if so, you can file them flat again.
By the way, make sure it has the "coffer dam" (center raised section on
bottom piece), so if the gasket does leak, it won't drain into the
engine.  Early pumps did not have this & should not be used.  There is
no way to tell from the outside- you have to take it apart to see it.
Since the 5 holes do not line up symmetrically, I always use some small
8" garden spikes to slip in a hole as I remove the screws.  Otherwise
lining them back up can be frustrating.  There are a lot of different
units out there, most are aftermarket.  The original ones are the light
weight aluminum.  Most aftermarket are heavy cast units weighing almost
twice as much.  One shouldn't have to crank down so hard on the screws
that they strip.  Once they do, though, the longer screws with a nut
work well.  I keep the screws on my spare with the screws backed off 1/2
turn to help eliminate warpage during storage.  I tighten them just past
snug after installation.  After a few heat cycles, I check tightness
again and adjust, if necessary.

For the fuel pump.  If it's leaking from the sides, try my suggestion
below.
If it's leaking from the hole in the top of the pump the gasket has
failed, vendors no longer carry rebuild kits as they were as costly as
an entire new pump.  A lower diaphram failure will fill your crankcase
with gas, never good for the engine.

Disassemble and check the gaskets for tears.  If you find both are in
good shape you can re-assemble.  Use longer screws during your
re-assembly, with nuts and lock washers or nyloks on the bottom side.
The housing is white metal and it's not unknown for the threads to have
insufficient clamping force to prevent leaks.

Regards,
Joel

I cleaned my timing marks better, however I only found the 0 to 16
marks. I looked at the block numbers which are partially covered by the
sheet metal.
I did make out a W in the code where I should have an RK (I think)
followed by 6 numbers. Are the last six numbers supposed to match my vin
6. They don't on this car. I'm not sure what engine this is? Probly very
common. In front of the W looks like two characters First:1 or Y or T
(?)only half visible and 2nd: 6 or 8 (bottom half) then the W. It can't
be a WA WB or RW.
I don't know what I have, but I will set my timing to 14BTDC.

 I just checked and the dwell was low ~22, I got it up to 30 with a .016
gauge. Although I thought the points looked new, I found they might need
replacing. The timing was 8 degrees.

 In the process of this, I also found, the V.A. leaking. While it was
running I disconnected the vacuum line, the timing AND RPM didn't change
however, when I plugged the vacuum with my finger the RPM dropped rather
significantly.  Leaving the line open or plugged in resulted in the same
RPM.

 Therefore I will fix the points and dwell and set the timing to 14
degrees.
Plug my VA line and ignore it for now. I will also rebuild my other carb
tonight.

 By the way, my fuel pump started leaking at the rim. Can I just replace
the gaskets? Like I said, this is a parts car for now and I'm just
tweaking it.
