The car is a '74 2.0l, trying to fix all the items wrong after purchase.

Have found the following items bad and have replaced them:
- MPS
- AAR
- Decel Valve
- CHT
- Spark plugs and wires

I have a bogging/lack of power at about 3000 RPMs, I assumed it was the TPS. But, testing it with the 20 click method I get all 20 clicks consistently.

My question is, is this a valid test to ensure the TPS is good?

And if no, how else should I test it?

And if yes, what else could be wrong to cause the problem?
