Everything's hooked up and egr is working. Bumped timing up to 10° from 6° and no pinging. Use to ping with anything over 6°. Tried hooking up the vacuum advance and it started pinging. I can't figure that one out. It has a 26° reluctor so I should have 36° total. I don't have a tach but revved it pretty good and it only went up to 20°. Might try some weaker springs. Pulled out a spark plug and it was black(dry). I had 59 jets and dropped them down to 51. Now it misses on acceleration so will put in some 57's. Probably will still be rich so need to find some 53-55 jets. What do you guys have in your carb? Not sure how to check power valve vacuum but doesn't seem like it is leaking. I have 3 of them but not one has a color code on it. I'm sure I will improve my fuel mileage but now have done so much I will never know how much the egr helped. I guess it all works together though.
