All good thoughts there.

Kodioneill,

The chassis is a 77 w/ an 80 engine enlarged to 3.2 w/o lambda and using a points dizzy.

Milt,

Not out of the question. I'll still look for leaks.

914efi,

The AAR, AAV and decel valve are certainly prime candidates for air leaks. The decel seems to be working because the revs hang up before dropping. The AAR seems to be working because from cold the revs initially stay high and gradually fall to spec idle speed. The AAV is suspect since the car takes a few tries to start from cold, so the sensor plate may not be raising @ cold start.

After trying various pressures during tests last fall, my mech and I both came to the conclusion that 3.4 or so warm created a too lean condition, and that about 2.4 warm was required. I had someone clean and reset the large plug to get 2.4 warm. I don't think they shortened the pin. The small plug was set to get .9 @ 15C.

I hear you. Standard practice is to always check ignition first when troubleshooting supposed CIS issues. Strange thing happened yesterday: after adjusting the mix, the engine initially didn't want to start. First time for that. No sound, no crank; nothing. Then it fired right up and was OK from then on. I smelled a faint "burned" type smell from near the coil and dizzy. It's possible it was a short as you had. Checked all wiring visually and all seems OK.

Tony,

You have to spell it out for a DF like me. I guess I need a Schraeder valve or similar installed somewhere. Where would be best? Then apply an air hose to it while the fuel pressure gauge is in place and watch the reading for 15 min or so?
