Exhaust work and new voltage regulator

Brothers muffler shop is just over the tracks from my home.  We needed a nearby shop, because our plan was to drive header-only to get the rest of the exhaust connected.  They did it while we waited and the price was right!

Now that we had an exhaust system, we went for a short drive to warm the engine so we could advance the timing to 12 degrees BTDC, and adjust the idle mixture screws.  We also rechecked the fuel pressure, warm, and it had dropped to around 2 psi.  The regulator adjustment worked much better, with a warm engine.  We set it to around 2.6 psi.
Since we had a little extra time, we checked the running voltage at the battery and it was approaching 16 volts while revving.  I had purchased a new voltage regulator, from Rockauto.com, for about ten bucks.  We installed that, and it kept the voltage below 15 when revving.

Fixed the turn signals

Image
When we purchased the car, it had no working turn signals.  We checked for a blown fuse, bad lamps etc and then drove home from Seattle without turn signals. I found a schematic online and used it to isolate the problem down to the flasher / turn signal relay, or a wiring problem after it in the circuit. The relay had a very questionable repair at some point, because the output connection was a very thin piece of steel or tin.  After opening it up, I found the repair was not soldered -- only glued! We will see how long my repair lasts...

New exhaust manifold gasket set

Image
I knew there were a few exhaust manifold mounting studs missing, most likely with stripped threads on the aluminum head.  I replaced all of the studs except one, and had to repair three holes with M10 x 1.25 heli-coils.  With the new gaskets and a good mount, the exhaust manifold was no longer leaking at the head.  Unfortunately, there was another leak at one of the air pipe flanges.  In order to replace that gasket (which was new) or to add another for more thickness, we would have to remove the manifold again. 4 out of 7 studs = leak I brought the manifold to a local auto parts store with a machine shop, for resurfacing The center stud was a little questionable, so we added a jam nut for now

Weber Carburetor install

Image
Today, Kyle and I installed the Weber Carburetor that we purchased from LC Engineering.  We also removed and plugged various obsolete vacuum ports and a few unused water temperature sensor ports. The linkage adapter that was supplied with the kit was too flimsy, in our opinion.  The weber carburetor linkage is about an inch farther away from the firewall, but the stock linkage was able to hinge enough to connect to it.  That hinging seemed to be causing a little binding, so we figured out a way to extend it (not pictured here, should be posted soon).  We decided to reuse the stock linkage connector, which was not keyed.  Since it needed to be keyed to prevent slippage, we cut the keyed section out of the Weber linkage and tack welded it on over the existing hole. The new carburetor has issues with its linkages sticking (not returning completely to the stops).  I plan to call LC tomorrow morning to find out how we can remedy that.
