Heres a picture of the engine back in the car. Dont judge me about the poor sticking olds rocket 350 sticker 😁

 

Thanks for the idea to check the CSM, i have a 71 lying around.

I will take a look in there.

And, for sure, im going to take a look at the timing again.

 

The carb works good at idle. No bogging or going up and down with rpm. At first, i adjusted the screws 3,5 turns out, drove the car to warm the engine up and then i wend a few 1/4 turns more out to search for max. Vacuum.
