Just to follow up a bit on what Scirocco said, you can check the rod for straightness by using a couple of V-blocks and a dial indicator if you don't have a lathe. Lay the rod on the V-blocks and drop the indicator on the rod. When you slowly turn the rod you will be able to see any error in it and you can adjust it with counter pressure with a press or even a hammer. Just don't get carried away hitting the rod. I have done something like this in a drill press and use the spindle to apply pressure to the rod to straighten it. It works very well if you take your time.
Many less-well-equipped hobbyists don't own V-blocks or dial indicators.
An alternative would be to place a sheet of glass on a flat tabletop, for instance, so that the glass is evenly supported underneath, and slowly rolling the rod across the glass while observing any gaps that appear & disappear as the rod is rolled. A grease pencil or felt tip marker can be used to mark the high spots.

I know the rod is straight, I see the same miss alignment from both directions .
When I have it together it will spin but not as freely as it should be .
I do not think it is really worth the money to align thes bushings.
If the rod is straight and it tightens up when put through the bushes on carb plate, it surely must be the plate that is at fault and must have a twist in it, now you have to ascertain which one it is and straighten accordingly.
