I'm still going nuts with my son's '71 142. To date: 'get good spark, all ignition parts are new or have been checked, cleaned, set (new cap, etc.) when electronic ignition was installed before current project. Valve clearances set a few hundred miles earlier. 'have checked for vacuum leaks and it appeared there was one at vacuum hose connection to carburetor port. I replaced vacuum hose and no more leak. No leaks apparent at carb/manifold or manifold/head junction or at either end of the hose (or the hose itself) going from the brake booster to the manifold. The car ran as well as could be expected with the Weber set-up PO had installed. We changed to SUs at the same time we converted from automatic to manual tranny. That's when the problems started. The car won't run worth a hoot - rough, no power and timing has to be severely advanced for car to run at all.

Carbs re-bushed and all parts move smoothly, float valves work properly. Fuel mixture set for initial running as suggested in Haynes. It's gotta be something simple that I'm overlooking and that's the most frustrating part. The bloomin' engine is simple enough that I at least should be able to get it to run.

The worst part - sob, sob 'son is gonna take the car to a shop ifn we don't git it fixed right away.
