I have it in the garage not hooked up yet. I was going to make a set of sedimentation buckets for the waste water.

AFR-Volts Chart
You also need to track the 12V voltage as the AFM/ECU does this and compensates for running at 11.5V to 15Vish range.

I also like the sunroof borrowed from a Winnebago. Must be real quiet at highway speeds. At least there are 2 more inches of headroom!

Do you have a unisync to verify the flow is balanced when the piston lift is balanced? That would be interesting at 2000 to 3000 rpm.

Cutting is better than hammering... there are bearings in the middle.

Gravel rules ? ollie, I'm keen to see if matched height equals balanced air flow. Please keep us posted!

SU Carb Sync Kit
There are O2 sensor fitted pipes that are inserted into the exhaust to sample the gas. To balance the fuel and air, there is a trick: lift the back piston all the way up to add 100% more air and no fuel to the air/fuel mix gulped by the front carb. The car should be able to chug along on just the first 3 cylinders. A normal a/f at idle is ~14.7 but by adding more air, it will jump to ~29 while chugging. Repeat by lifting the front piston and running on the back 3 cylinders. Adjust the jet heights to get the a/f ~ 29 on each carb and exactly the same. Double check and re-balance the air flow then repeat the a/f adjustments. It is iterative. You can either do this at 700rpm (idle) or at ~2200rpm (off idle). I prefer the off-idle optimization as this is where balance is critical and driving is more fun than idling ?

It will be interesting to see the results comparing piston lift to air flow. Both are different parameters that are related. Piston lift due to suction due to air flow can be different in each carb for the same airflow due to piston binding or lack of sealing or needle setting. If you can get your hands on a wide band O2 sensor, then run the car just on the front carb, then on the back carb and compare a/f for each. It should be ~29 for each.

If the pads are seized to the shoes then some heat will help. Watch out for asbestos dust!
