Old man with old car, new here with questions

Ok you gave me more good information. 1) You are right about the divorced choke working too fast without a modulator. 2) Regarding the power steering gear box adjustment I read the manual and researched on line before I adjusted it. The usual statements actually tell you to go in small steps and not to go over 1 full turn when done to prevent lockups.
3) Will a BBS carb for the 225 Cu in engine work on the 170 Cu in? The throttle opening is a little larger ( I read that from one of your comments). Does that matter? 4) The temp gauge works and the fuel gauge will move a little and then go back to empty. I realize that the sender or the gauge could be bad. Hate to pull the tank. The good news is that the tank is full and so far not leaking.
