My engine of my Opel ('(78) started backfiring in the carb.
I checked ignition timing, valve timing, cleaned the carb. But nothing
seems to work. At idle the engine sounds good, but at higher revs the
backfiring starts.

Who has an idea?

It sounds like u have a worn cam lobe. Pontiacs have
a really bad problem with this. Its probably an exhaust lobe. Pull a valve
cover and look at the rocker arms while its running and u should be able to
see one not moving up and down as much.

Cut down the detail to increase the frame rate and all of your backfiring
problems should disappear. I hope that this problem will be removed if a
patch is ever released.

Check for lean fuel mixture (clogged jets) and vacuum/mechanical advance
operation.
