So I replaced the spark plugs wich expectedly did not change a thing. After sitting a while the engine started, but ran bad again and not for long. Compression testing the engine gave me values in the 130psi range on all cylinders. I ordered the entire ignition system to see if the problem lies there.

Edit: I did not order the entire Distributor, only cap and internal parts.

Edit 2: I tried to start the engine with starting spray, to see if it’s something with the carb, but it did not change anything.
