Hello all. I'm about to install my rebuilt engine in my restoration project, and wanted to adjust the throttle linkage as per Section A.37 of the Bentley manual before installation while the throttle shaft bolts are all easily accessible.

I read the Ron Phillips Moss Motoring piece from 1999 (Link Here) which offers the helpful suggestion "Be sure you have all your flooring pieces in place—tar paper, jute underlayment, carpet, and doormat, or whatever you are using this week. Why lose up to an inch of travel once you’ve installed your interior". Uh-oh. I have no interior in my car, and was planning on doing this as a much lower priority than installing the engine and making sure it runs (hoping of course I don't have to remove it but protecting for the fact I may).

Any ideas for how I adjust the throttle shaft without the interior in the car? I actually do already have the interior bits (carpet and jute anyway, no underlay) in boxes but haven't opened any of that yet as I want to keep it tidy and packed away safely. Do I need to lay the carpet and jute out to get a proper estimate of the impact? What should I do to adjust for the underlay (which I don't have yet. I was planning to use a thermal barrier like dynomat and not tarpaper). Any advice appreciated. Seems this may be an unpleasant job after the engine is in the car.

Hi Rob,

I pulled this info from my Workshop Manual, it should give you a direction to follow.

The photo is of my 1960 BT7.

The linkage was always like this with the HD6 carbs so try to mimic this arrangement.

Good luck,
