Model T Ford Forum: Forum 2017: Difference between Kingston L2 and L4 Carburetors

Is there a visual difference between the L2 and L4 carburetors? I know internally there is, but I have not seen any comparison photographs posted on line. I assume the earlier L2 was manufactured with a brass body casting. But I read that early L4 carburetors also had a brass body. My understanding is also that the L4 is preferable.

Never mind ... found the picture essay on carburetors in the McCalley Model T Ford book.

When I bought my 1915 Runabout it had a Holly NH on it. The original Kingston L2 came with the car. When I spoke to Stan Howe he explained the Kingston L2 was not a very good carburetor when new, he recommended a Holly G saying it was a very good carburetor, used for many years of model T production and would correct for my car.
Found the correct vintage Holly G carburetor, had Stan rebuild it for me, made a correct choke control rod, had it plated and it is very reliable.

Ron: Nice carb, where can one obtain that ball and socket throttle rod attachment? I assume that is unique to the carb and was provided by Stan? thanks, jb

James;
It's a year thing not which carb is on the car. In other words, did not matter if Kingston or Holley they both had a ball and socket attachment. Check the encyclopedia it should tell which years used what.

I have not checked vendors, does anyone sell these? jb

Try Bob's Antique Auto.
I bought a throttle rod like this from him about a year ago?

Yes, the early L-4 is brass...mine is and so is the float. The chief difference between the L-2 and the L-4 besides the reliability and performance is the damper nut on top is larger on an L-2 than on an L-4.

I love my L-4, never had a problem with it other than when I do something stupid...like strip the bowl nut threads...did that once, got a second body from Steve Boothroid in Canada.



And yes, the head is purple, lol. :-)

Here is the correct end for your throttle rod.

I failed to mention, the swivel joint end goes on the end of your commutator rod at the end of the steering column.

After doing some research on my own it appears Larry is correct. The swivel I have on the carburetor end of the throttle pull rod is wrong. I need one of the screw on bent rod shown above. Here are some images taken from a 1916 parts book.

L2 on left, L4 on right. L4 switched later to a cast iron body.
