I am trying to put on a conversion unit from Lang's(they are closed) tonight. For those of you that have used this unit before I have a question. Do you just use the vaporizer needle in the NH carb so you can use the 26-27 adjustment rod and then a wire from the rod to the choke?? The instructions that came with it say nothing about it and it gave the name Bruce Ryer to call and the phone is out of service.
Conversion unit operates the throttle using existing vaporizer linkage over top of head.
Everything else is NH.
Dash choke/mixture rod may need to changed due to length.
Hope this helps.
The Vaporizer and NH adjustment needles ARE NOT the same !
Are the needles the same except for the top part?
The needle in the vaporizer is much, much shorter than the NH.
What have others done to convert the mixture rod and choke to without altering the firewall with a bell crank?
No modifying necessary, Larry. Use the late style NH adjustment needle with the swivel - same as the Vaporizer but longer needle like Dave stated.
The Dash mixture and choke rod 4129B is same for the NH and Vaporizer. In my case I used a different length.
1)Model T Carburetor adjusting rod - 4129B
2)Carburetor. choke rod sleeve, holds choke wire 4591
3) NH spray needle assembly with u-joint and sleeve 6213B.
Hope this helps
If you look in a 1927 parts catalog, you will see at least 8 different lengths of carburetor adjusting rods. Make sure you get the correct one.
The float valve is the same as an NH. You also will not need that long elbow any more, as you will be converting it to the common elbow. Lastly, you will need to move the throttle lever down the steering column to the regular place. Maybe you will luck out, and find Ford already drilled one for you!
The u-joint adjusting rod was introduced the last four months of 1925, and the bell crank was eliminated, but the adjusting rod is unique to 1925 only on the roadster and touring. The sedan models, and TT trucks will have a different one yet. You will probably also need a different throttle rod to go through the block. Hopefully, your block is already punched out. If you are using engine pans, and your car is a '27, you will probably already have the two holes in it.
