Looking for advice. Having problems with 1970 Coougar w/351c. It is hard> to start and uses lots of gas (<9.something mpg in city, used to 12 or
so).> When strarting cold, it appears to flood easy as you can smell gas at tail> pipe. Recently put kit in carb trying to fix this and found float orings> pretty much gone (crumbled when removing) but can't say much improved.>
Changing the plugs helps with the starting for a while but not long.
Pulled> plugs and the front 4 (1, 2, 5 and 6) are black with soot but other 4 are> ok. This is after about 500 miles on new plugs. The motor was rebuilt> about 10 years ago with a used alum edlebrock dual plane intake and 600
Holley 4bbl. There are no vacuum leaks to the outside along the intake to> head seams. Don't think there are any other vacuum leaks.>
What would cause the front 4 plugs to run rich but the back 4 be OK? I'm> 99% sure cylinders 1,2,5 and 6 are not on the same side of the dual plane> intake so does that elimnate the carb having a problem left to right? I'm> tempted to get a new carb but would like some confidence that will solve
problem. Since the carb rebuild, there is a flat spot in the throttle

Any advice appreciated. I will try to post pictures of the 8 plugs later.> thanks, bobby> bbusselmanCoyote at hotmail dot com (remove the dog to send email)>
Finally got some pictures posted. Per all of the posts, Carb is being
blamed. Still not sure how the carb can make the front 4 cylinders richer
than the back but that is what is happening. The pictures are at
http://mysite.veriz­on.net/blondechick/s­parkplugs.htm . I wire brushed #1 to
see if it would clean up but it originally had black fluffy soot on it.
