Re: Idle (passive) jets

The pilot jets are not adjustable, just screw them in. They should have O
rings on them.

Setting these carbs up properly requires a fine touch and a good deal of
practice. Here's my standard recommendation on this: find a mechanic with
relevant Porsche or high-performance VW experience and a lot of it. He'll be
over 50 and expensive, and if he speaks German as his first language it's a
plus. Pay him what it takes to get your carbs in tune, watch carefully and
ask questions while he's doing it. Learn all you can about the process in
general and your carbs in particular. If you study carefully you'll be able
to keep them in tune from there, and it will be worth every penny. Without
knowledgable help, this process can be extremely frustrating, particularly
for beginners.

You know you *have* to study a good manual on this first, right? And you've
got the tuneup procedures covered, of course -- valves, dwell, timing,
fuel -- plus careful inspection of your carbs to be sure that they're clean,
they match down to the jets and they're the right ones for your car. Don't
trust *any*thing -- any detail missed here will be at least a couple of days
of frustration that nobody needs. You've also made sure there are no intake
leaks (Butterflies need rebushing? Do it now or you're wasting your time)
and your balance pipe is right.
