Thanks Mick- have the motor out for a refresh, and a few upgrades. The carbs are on my bench- so I'll check which jets are in them as long as they're laying there. I'm not sure which end it's rich on- I have a 5 speed with 3.54 Dana. and tall 295/50/18's- so 70 is just under 2,000 RPM. I like to get on it- but not flog the crap out of it. Little idling as I live on a highway, work in a small town. The carbs come on at the same time- but I could adjust the rear to hit later with the linkage. It doesn't burn your eyes- but I can taste the exhaust some after a while.

I would lok at the spark plugs to see if it is rich, lean or just right at idle If your heads didn't have the spark plug tube seals they may be covered in oil, try and look though that to see the color on the porclyn and the ground strap, if there is any small dots, pepper or bright, it is lean. If they are both black it is rich I'm sure that there are more than one example of proper spark plug appearances pictures to look at onthe net Many things contribute to what the spark plugs look like other than the jets in the carbs. Things like gasoline quality and age, spark plug heat range, ignition timing, spark plug wire type and condition, ignition type and condition,air cleaner condition, choke adjustment and so on It ain't easy to get them all perfect but it isn't impossible either, you can do it First you got to want to make it better As far as the throttle linkage adjustments to use, try it both ways and then decide

Check all of the plugs and keep track of what holes they came out of. Does the intake manifold have 4 holes in the carb plenum or open? I think those are 750's and they wouldn't open on a stock manifold.

I went out while she was still sleeping, and looked at the some. Rods are all 7147"s, and the # on the base ion the front are both 2540 9756S. Now- I did say was not a carb guy- so don't laugh too much. Where's the jets?




Those are both chrysler spec 750's ... just an FYI ...
