WOW a nice ending for a persistent trouble shooter. That was a very unusual problem to solve. My hat is off to you!!!

Here is @blodi's similar config to yours: It is fairly flat and around 12-13 like yours but a big dip to ~ 10 at the start.

Do it in two steps: 1. Melt some solder on the tip of the iron then place the tip under the wire in the harness. Let the wire heat up then feed solder into it. Keep the heat on it. Congrats you tinned a wire. 2. Wrap the other wire around the tinned section and do the same: Melt solder on the tip then heat the two wires while feeding solder... don't be shy on the heat time. It can take a while. Just keep the iron on the wire.

@moelk Nice A/F. What jets, chokes, fuel level etc are you using? Looks like they had smoothing on. Very similar to @blodi's

194 HP is nice! @blodi had similar with 45's, cam, and L28.

1. Clean with vinegar and tooth brush until copper on both wires is bright. 2. Pull back enough insulation on the exposed end so that its copper can be fully wrapped around the exposed copper in the harness wire. 3. Solder the two together. 4. Insulate with electrical tape.

I like to paint phosphoric acid on metal then wipe with acetone when dry.

Try disconnecting the connectors 1 at a time to the lights switch/wiper switch in the steering column and see which one causes the problem. Watch out for the power cables from shorting.

I like the Uni-Syn for high RPM balancing check when the air flow is high.... but the STE Synchrometer is very accurate and repeatable. It works nicely for SU's at ~ 7 to 11 kg/h (depending on calibration) for idle. You can pull the rubber lip out a bit to expose the holes in the throat then dial up the rpms so that the front carb is at 35 kg/h then move to the back carb to adjust the balancing screw to get the same 35 kg/h Note: The BK Black version is 1-35 kg/h but the SK Silver version is 1-30 kg/h. The black one is better for SU tuning.

Picked up a lot of NOS parts . Check out the classifieds.

Looks like a paint dab on the hose to the manifold from the throttle control opener and an accidental swipe on the curly hose to the servo diaphragm. Note the early braided choke wire.

Monochrome photo of possibly HLS30-00003. You cab certainly see the yellow dabs of paint on the t/c rod nuts where it attaches to the control arms. Note the oil pan does not have the patch.
