I have to change the throttle rod on my 1927 Ford.
What is the procedure please? The arm on the throttle rod need to be lowered for a newer carburetor.
Daniel - When you refer to "the arm on the throttle rod" are you referring to the approx. 1" long arm on the throttle rod down next to the engine? It sounds like you may be converting a car that had a vaporizer carburetor to the more common Holley NH or Kingston type of carburetor which would require this short arm to be re-positioned further down the throttle rod. Is that right?
If so, you can free up the short arm by removing the pin holding it in place by knocking or drilling it out, then slide it down to the new place it needs to be and drill a hole in the throttle rod and pin it to hold it there.
By doing this you don't have to remove the whole throttle rod from the steering column etc. thus saving lots of work.
Remove the steering column from the steering bracket on the frame.
First remove the spark lever from the end of the spark rod. Drill out the tiny rivet there.
Spray some penetrating oil on the spark and throttle rod ends where they enter the bracket to loose up the rods so they will slide away as you retract the steering column.
Remove the pitman arm, by removing the cotter pin the nut, save the woodruff key, smack off the pitman arm or use a puller if needed.
Unbolt the steering column from the dash, 4 bolts and nuts, remove the horn wire from the terminal block.
Pull away the steering column until the wheel lays on the front seat back.
Now you have space to remove the throttle lever, with same process as removing the spark lever, re-position the throttle lever where you want it.
Reverse all in to install.
Or, to keep from doing all that, trip to the hardware store or you garage drawers and fab up a clip on or clamp on bracket to substitute for the Ford throttle lever, .....may be easier
You can buy a bolt on bracket from suppliers, Lang's sells one for about twenty bucks.
