Welcome!

Did you get any maintenance records with the car? Do you get the sense it has been kept up and driven regularly, or has it been sitting for a while? Is the stock CIS in place? Do you have any experience working on cars and aircooled Porsches in particular? Will you be doing the work or looking for a shop to work on it? Does the engine run smoothly and car drive well (no stuttering or hesitations) when cold?

A lot of things can cause high idle.

Number one by far are air leaks. Tons of info here about how to find and fix. Use the search function.

Yours is not too far off where it should be. Both cold and warm idle are about 200 high. Do you know how to turn the idle down using the idle adjustment (air bypass) screw on the upper left side of the CIS? This is kind of cheating but you cant really hurt anything by turning the screw clockwise to reduce the idle and see if you get lucky. Keep track of how much you turn it so you can put it back where it was if necessary.

Timing. Fuel pressures. Fuel delivery etc etc.

Lots of help here. Ask questions. Get a Bentley repair manual. Read a lot.

And shoot us a pic of your new ride!
