Dual quads versus big hammer!!!...

So hoping to get out and do a little more experimenting with these carburetors today. First I'll warm it up a little bit and take it for a drive and re remind myself where everything is at. Then I'd like to try some stronger step up Springs to see how they react. I have a much smaller set of metering rods I would like to try in the front carburetor as mentioned in the corded post from another forum above. It won't be till Tuesday till I'll have a semi matching set of rods...
Right now I have 62-54 rods in both.. after some spring changes and testing I may go back to 60-52 rods.. I have a set of 58-44 rods that just came in and they said 58-50 rods that should be here Tuesday...
I think I'd like to try something like in the above post that I copied where I put the 60-52 rods in the back with a Little bit stronger spring and the 58-44 rods in front with a little bit lighter spring.. and of course on Tuesday matching the rear carburetor with the 58 50 rods to keep the idle circuit even in the front and back...
