1.7L high idle
I drove my 1.7L 914 last weekend and experienced no problems. This weekend I took it out and it is idling at 4500RPMs. I let it warm up and drove it a couple of miles. The idle would not reset. The throttle cables look fine. I may have a vacuum leak somewhere, but I don't know how to isolate the issue. Any thoughts?

Carb spray is a good way to isolate vacuum leaks. With engine running, spray it at certain areas. If idle changes, then you've located the leak. Great way to zoom in on a possible vacuum leak

Timing and carb adjustments is where Id start.
