Hi guys-hoping to get some sage advice here on what's going on. I am picking at the 1973 1.7 L D-jet car and when I was test driving her today she did not want to return back to idle.

When you accelerate in first gear up to about 3500 or 4000 RPM and then take your foot off the gas the RPMs stay at the same level or climb slightly and then only slowly drift down.

She starts fine and will idle at about 1000 RPM, air bleed screw is close to all the way in.

There is an aftermarket return spring on the throttle assembly but appears to have the right amount of tension. I took the air cleaner off and when I manually actually the throttle it appears to settle down faster than when I do it with the gas pedal.

The pedal does not appear to be binding on the carpet or interior trim.

Any ideas for me?

Thanks!
