Cis help!!!
 

Hi all.
Just got a '77 924, first Porsche, had 5 Triumphs in the past.

The car starts fine, but has no power If I try to drive, it bogs, spits, backfires and then stalls. It will start back up but that's all.

I've turned these adjustments all the way clockwise (photos)

If someone could suggest how many turns counter clockwise to get to a base to start from or anything else I would appreciate it greatly.

This is my first post anywhere, please have pity..

Thanks in advance,

Rob
