    Hi,
    i have two items in one thread, simple ones:
    1) FD has the CO mix screw hole... I could not rotate the screw yet (cant find a long 3mm hex that fits with the correct angle)
    but there should not be a sealing cap there? I put some fuel on it... and entered the FD without issues... so if fuel can get in, air too... so this is a air leak for sure.
    Please confirm.

    2) also, i was swapping spark plug wires, and found the rotor cap and wires are numbered 1-4, but when the wires go to the plugs, they go 1-4 2-3, 3-2 and 4-1.. .inverted... is that ok?

    Yes -- even a simple rubber stopper would suffice (and you'll probably have to retweak the idle RPM speed and the idle mixture if those were originally set with it missing). This is a typical one (that you should be able to find -- search Volvo and VW parts suppliers):

    Maybe a supplier mismade/mislabeled those spark plug wires -- the cyl #1 wire has to be the longest wire and the cyl # 4 the shortest wire. If it's running well, I wouldn't worry about it.

    ok BAD to know I had an air leak all this time :(

    the 1-4 labels are in synch with the distributor cap numbers...

    so distributor cap and valve covers are the issue, not the wires itself

    ok found I took the wrong wire set... both are labeled 1-4 but one is inverted in lengths :)
    why not use 1-8 instead ot two 1-4 labels is a mistery :)
