If you have a real long stretch of road where you can wind the car out then try this.
Loosen the secondary air flap so there’s minimum tension then take the car on a drive and wind it out slow. If it still flattens out at the top 3rd and in 4th then you have a fuel delivery issue, not a issue of the flap opening too fast or too late!
Ok, so I was able to get out and try this. Winding it out slow, it starts to bog at high RPM going from 1st to second and from 2nd to third.

Punching it from a standing start results exactly the same with it bogging from 1st to 2nd and never shifting. Same thing with doing 60 and punching it....goes for a bit and then bogs at higher RPM in 2nd before it reaches 3rd.

As a side note, when I parked it this time and gave it a little rev, it backfired through the carb and then the rpm increased a bit.

I'm going to change the fuel filter as it may have picked something up and then after that, I think my issue may be the sock.
