the 40 mile ride gave me time to think on it again,i have come up with this simple fix.
take the 2 flat bars,cut the one so it does not have the slot.
drill 2 holes to bolt them together,use a longer bolt with a stack of washer to make the off set and fit the back of the slot to the carb stud with the rod from trans pulled foward..(flip it back around like you had it first)
that will make the flat bar long enuff,move without the throttle stud and have the off set to line it up with the carb stud and the intake bracket bell crank..
very simple and no welding
you already have them bolted to gether so just spaceing them apart should work with no problems.
i would go back to the taller bracket and ditch the washer on the intake bolts.
close the slide up on the rod from trans up so,then make the flatbar with off set the length you need,this will aloow for adjustment on the bell crank like stock.
give that a try and see what it does
