For Vowel Art, RHD Holley Carb Notes

For Martynn

Here are some pictures of Holley G RHD carburetors for information. Here in Nova Scotia and New Brunswick, Canada, we drove on the left of the road up until 1923. So, the standard Canadian Fords shipped to us were RHD. I sometimes get a bit carried away trying to pick up any RHD parts that I see when scouting for T parts. I got a bit really carried away and collected up several Holley G carburetors when I was restoring my ’15 RHD Canadian roadster. A few of the Holley Gs were RHD style. The only difference in them appears to be the throttle arm. For RHD, the movement has to be front to back of the car, where for LHD the movement is left to right of the car.


I also believe that there is another difference in the Canadian Holley G carburetors. At the time that Ford and many of the suppliers started to add “made in USA” to their parts, the import duties into Canada for “non-Canadian” parts was high. So, in many cases vendors opened Canadian assembly factories to help get around the import tariffs. Anything marked “made in USA” was obviously an import of course. So, I think that Holley used a different cover plate on the Holley Gs sent to (or assembled in) Canada. The covers just say “Holley Bros” and a patent date. There is no “Detroit” on the cover plate. I have found several Holley carburetors with this plate and a couple versions of the cover plate which would follow with the early to late Holley G models, such as brass and cast iron versions. I would be interested to hear what those in Australia might report on what they have seen on their Canadian imported cars from this period.

Pictures below a couple Holley G models with the RHD throttle lever.

Part 2. The spark control linkage.

The linkage from the spark rod to the carburetor is awkward at best. At first glance looking at the lever on the spark rod (the left lever on the RHD cars), you wouldn’t think that it would even work. The linkage from the lever to the carburetor requires the use of a swivel connection and then a bent rod from the swivel to the throttle lever. The bent rod has to go behind the intake manifold and be able to move back and forth without jamming on either the manifold or the valve covers. It can take a while to get it right. I only had part of my original linkage so the rod from the swivel to the throttle arm is my best guess based on some research and what would actually work. These pictures are of my ’15 with a 14 style Holley G with the patent pending all brass carburetor. Sometimes the parts here lagged a bit behind the latest version in use in the US.

Part 3

Kingston RHD example. Here are a couple pictures of a Kingston RHD. Similar to the Holley the arm is designed for the front to back movement. But it does appear to be a slightly longer arm than on the RHD Holleys that I have. It also doesn’t have Detroit or USA anywhere on the carburetor.
