comment Mercedes W123 engine “jumpy” when cold
I have ordered a rebuild kit for the carb and while replacing the seals I will look into repairing the choke. Will see how it goes.
comment VW Jetta II - engine misfires when climbing a hill
The ignition timing seems to be correct - I checked it with a timing light. Ignition advance also seems to be working - both centrifugal and vacuum operated. The broken vacuum line goes to a deice on the intake (before air filter) which selects cold air or hot air (heated by the exhaust manifold). The fuel pump is mechanical, but the next time I will try to check if there is any fuel in the carburetor. As for proper components - I try, but not everything is available.
comment Engine does not have enough power (and has limited RPM)
While I did not risk taking the carb apart, I finally found a competent mechanic who managed to repair the engine. And yes, the diaphragm had two holes in it. Now the car is really quick (did not test top speed (yet), but acceleration is really fast).
