Re: Ignition Timing



I found this fella's video useful on this topic ... and kinda funny at the same time :-)

No idle mixture changes is also due to excess throttle plate opening. The carb starts pulling fuel thru the transfer slots and bypasses the idle circuit, hence no mixture screw response.

Not being much of a carb tuner I have had questions about this Holley Street Avenger since trying to get it set up on my car.  I bought it used on ebay.  I found that I could turn the air mixture screws in all the way without making any diference.  I followed the Holley tuning guide and did change the power valve to one that my results suggested I should be using.  The slots in the primary venturi seem to be partly exposed (eyesight not what it used to be) with the plates fully closed.  Not sure if this relates to what Mike is talking about.  But there is definitely something goofy with this carb and i'd like to get to the bottom f it.

I've heard some differing info over the years on ignition timing.  I was talking to MO recently, and the guy who set up his distributor on his machine made the comment that setting "x" was all wrong for a manual transmissi on.  So I'm wondering if there is a difference in what you do for manual vs. automatic.  Right now I've got mine set at 32* BTDC all in at @ 2500.  This is 440 primarily street driven car with a bit of a cam.  I had been running with the vacuum advance plugged off.  I recently checked the timing because I was able to borrow a timing light.  I had a crappy one when I set it before.  It was retarded about 8* so more like 25* BTDC.  So I reset it and the result was that it seemed to run a little better but I had developed a slight bog from a stop.  So I'm wondering where I should go from here?   Should I hook up the vacuum advance and reset the total advance?  BTW it didn't seem to make any difference on my issue with running hot in town
