Well, my car is up to it's old tricks again. Frequenters of this bbs have probably read and responded to my previous emails about my backfiring, 1973 911 with Webers. So far, what has worked for the longest is doing a full cleaning of the carbs. That lasted for only 100 miles!

I noticed a few different things tonight, as I've learned to be much more observant about the running (or not) of my engine :

1)The backfiring came out the right side only of my sport exhaust (nice 9 inch flame!), not back through the carbs.

2) The fuel pressure guage flutters a bit where it was rock solid at ~2.5 psi (single Facet fuel pump - small gold box shaped one mounted in the engine bay). Vapor lock?

3) The CDI box was giving its usual "all OK" whine when I heard a electrical like snap from somewhere near the coil or distributor. The whine changed pitch during the snap, which occurred 3 times. I cleaned the cap and rotor and changed the coil with no better running.

This is a new one for me. Possibly unrelated, but to I'll mention these anyway, my cockpit blower fan and high beams no longer work. Could this be related? I haven't checked fuses but I figured the more info I throw out there the better. I'm trying desparately to get this car running perfect for the Watkins Glen vintage weekend, which is a mere week away. Anyone else going? Hope I am!

Thanks,
