Rich, > Keep in mind that your carb has a split personality: "Idle" circuit "Butterfly valves open" circuit there's more to it that that, of course, but most of what you notice at idle is idle mixture settings AND/OR vacuum leaks. There is a guy locally that has a Sun diagnosticmachine and charges a buck and a half to feel your car up with it. It can even tell which cylinder is firing poorly on the scope! -Carnal knowledge of one's engine never felt so good! I had my carb rebuilt for $250.00 (the carb rebuilder referred me to him, and he does 4 cars per saturday session). I watched in wonder as he put the gas analyzer up the car's kazoo and proceeded to adjust the idle mixture setting. He also detected a miss on cylinder no 7, and that turned out to be the vacuum hose that led to the parking brake release mechanism. - That was that hiss under the dash that I'd been merrily listening to and ignoring for the last 6 months! The vacuum line plugs into the manifold on the no. 7 runner, causing lean when hole is present in vacuum lines on it!! Duh. Obvious? Maybe, but that $150 shortcutted a lot of brain activity, and that's worth something. David (who just wrote in) was there for that, too, and it was highly entertaining, from a car-guy point of view. Rebuilt carb, new fuel filter (!!!!), and a practiced hand to tune it, and the car is like silk at idle!! WOWEE! If you're in the SF Bay Area, call John F. Bishop at 650-343-4860 for a good time (carb-wise). He is in Burlingame near the IT'S-IT factory on 101. He had some apprentice that was bragging about tuning and how he'd been in this magazine and that and how they were testing some gadget and all that. I wasn't as impressed as that guy had hoped, but it made for encouraging background noise as I was entrusting my prize to john, because I'm stingy and hate paying labor fees if at all possible, but it was money well spent! -K Kenyon Wills ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
