Chapter 23 6/10/02
It seems like a while since I made an entry, however, I have not been
idle.... Just that until I could test things out, it didn't make sense to
write. Now I can tell you that the TurboStude is mobile again and
running under its own power! I have tracked down some pesky coolant
leaks and then noticed when I started the engine that something was still
leaking. The engine was hard to keep running, and the reason was that
gas was just gushing out the carb base and manifold and the top of the
accelerator pump. I had hot-wired the electric fuel pump as I usually
do to fill up the bowls after a long sit. Seems that the floats were
not working....? Well, maybe that backfire or pressure build-up which
abruptly ended my last outing was involved? Top off carb, found some
rather mangled floats!
Took the opportunity to change primary jets to 0.114 and secondary to
0.104. Put in some new, stock floats (I better make up some foam
ones....). Tried the car. A/F meter now off top end of scale for
O2 sensor and clouds of blue smoke. Top off carb again, changed
primaries to 0.104. At this point, I made up a better seal for the
accelerator pump too. To do this, I found a washer which, when ground a
little would just fit inside the depression in the carb top piece. I
found a little neoprene rubber washer with a "nose" on it which
just fit thru the hole in the washer. I peened the pair in place and
then epoxied it down. It bound a bit on the accelerator pump shaft, so I
gently sanded this (it is plastic) and then polished it. This is a better
seal.
Noted that the large bore vacuum port between the idle air screws was open to
the atmosphere! I have no idea how long it has been that way. I
believe that it had a bolt jammed into the hose which was on the port.
Maybe the "BIG BANG" popped it out as well, and I was just finding
out, since the huge gas dump was being offset by the huge air leak!....
Anyway, it is all plugged up again. At this point, it seems that the
car is stuttering a bit off idle and then with gradual pedal pressure it
accelerates like it is on a huge rubber band..... I think that I need
to adjust the accelerator pump again for different throw, maybe go a bit
leaner again on the primary and fool with the timing again.
Actually driving the car, the brakes really work well! The clutch
shifts RIGHT NOW and I think we'll stick with this rear-end
ratio. I actually can lay a little patch, though I was afraid to snap
the driveshaft (at least until after Back-to the 50's......). The seats
are really comfy. I hung the collapsed floats on the mirror like a pair
of baby shoes. Hood won't shut right. I think I'll take it off
and go "naked" again. |
