1.) I finally got a vacuum gauge hooked up to my stock '70 318 and after playing around with my idle mixture a bit, I only got it to go as high as 15 in-Hg. Is this acceptable? I do have the stock divided-plenum low-rise single-plane intake (BOO :angry7:) and I only got a reading on the driver's side plenum, but I assume it would be similar on both sides. I tested the cranking compression on cylinders #1 and #3 (didn't get to the rest) and it was around 92 psi, and I'd assume the rest would be close to that because my starter stays the same pitch when cranking for an extended period.
2.) I read in an article about converting an '80's truck smogger 318 2-bbl. to a 4-bbl. that most/all of the old 318 2-bbl's (no matter the year) develop a bad hesitation off the line that has to do with the carb. Is this true, and what makes it happen? My 318 has done this since I got the car.
3.) I'm putting some aftermarket gauges in my Duster and I don't know what I should do as far as wiring goes. Do I splice into an already-existing circuit, or do I create a whole new circuit? When I put my tach in I just hot-wired it straight to the fuse connections in the fusebox, and I know that's definitely not the proper way to do it.
