Quad carb setup information help

rod7515 said
Took the car out for a ride today. I will say that it doesn't seem anywhere near as rich as it did on the first start. I have the throttle plates totally closed on both carbs and idle screws backed out off stops. It idles at about 900 rpms in gear. Its a little low but doesn't load up at all and will sit and run forever that way.
I want to get the distributor out and check to see if it can be changed but I need to wait another 2 weeks before it can be done. I the meantime I plan on moving the timing up to see how it handles more advance.
My edelbrock synchronizing gage came so I will get that assembled to the top lid and see if I can play with that awhile even tho I will probably have to do it again once the distributor is changed.
During my ride today the I noticed a slight boog around 2500 -2800 rooms while driving. Again its very slight. I also plan on adding my bungs in my exhaust to see what ratio I have. How do I know where to put them to get the best readings? Should I put one on each side?
This is all new to me so I really appreciate the but help.
As for the distributor how did you come to the 6* distributor change and is that still the number you think is best?
Thanks Rod

What power valve are you using? That slight bog could be a lean spot because the power valve is opening too late or it could be a rich spot because it’s opening too soon. It could also be the secondaries opening a skosh too quick.

As for the 6 degrees...if we are talking about how I would do it, I’d start with 6 degrees of mechanical advance in the distributor. That’s all. Maybe 7 at the most.

When you have say 6 degrees in the distributor you double that because the crank is turning twice as fast as the cam/distributor. So that means at the crank you’ll have 12 degrees of mechanical advance.

So let’s just say you’ll end up at 35 degrees total, you’ll have 35 minus your 12 mechanical is 23 initial timing. If you end up at 34 total you’ll have 22 initial and let’s say you may end up with 36 total you’ll have 24 initial.

And I wouldn’t let the distributor add any mechanical advance until 2300-2400 rpm and it get it all in until 3300 or so.

That’s what I’d start with.
