Need Opinions. Have nothing to compare to.
Car had a new set of Champion RJ12Y plugs and a new Accel cap & rotor. The tech working on the car noticed it went a little rich in the middle of the first pull. He said he thought it might be dirty air tubes and shot some cleaner in four corners of the carb (Air tubes) and did another pull. The A/F mixture evened out and looked pretty good through the full pull so he didn't do anything else on the carb. He adjusted the timing up a couple degrees, then a couple more when he saw a drop off in horsepower so he backed it back down to 15 initial and 45 all in (mechanical and vacuum advance)
He mentioned that 30 degrees seemed to be a lot. I told him when I first got the car, the vacuum advance wasn't hooked up. Well, technically it was, but there was no vacuum to the port he had it hooked to, so essentially, it wasn't hooked up. The Demon carb has two vacuum ports on the passenger side, near the front of the carb. The front port has no vacuum, so I moved the vac advance line to the second port. The tech didn't try it with mechanical advance only.
