  • Looking for carburetor alternatives for a '61 Lark with OHV 6

    I've posted about this before, but didn't get much response... thought I'd try again.

    The original Carter AS carb on my son's '61 Lark with the OHV 6 has been nothing but trouble, and after a fighting it for a couple of years, I'm wondering what alternatives might be good. We've been through the original carb a dozen times and still can't get it to run worth a damn, I'm over it...

    Is there a carb that is a bolt on replacement, that is new, that will perform well on this engine? I have a new Weber 32/36 but it is too tall to fit under the hood with a two into one adapter and air cleaner. Looking for another alternative. I suppose even a professionally rebuilt Carter AS would do, but it seems like a poor design to begin with.

    Thoughts?

    Thanks,

    Pete

    Best bet is an adjustable main jet Stromberg BOXV single bbl carb as used on 1941 champions, and some mopars in the early 50's. It is a bolt on, excepting the air cleaner.

      Those Carter Model AS are a very good Carb. and THE preferred replacement for the "disposable" Carter RBS "Rambler" Carbs. used on the '63 & '64 OHV Six.

      The problem may be that you got one of those EARLY Model AS ones used on 1959-'60 Larks that were always trouble right out of the Showroom, had fires, Service Letters by the dozen and repair kits distributed.

      The one you want is the improved 1962 version. The Parts Catalog shows the Sub-Model of Model "AS" Carter you need.

        Not sure how to identify whether or not mine is early or late. It's been worked over by previous owners, and I think it is now beyond help. The accelerator pump doesn't work right, it will die when you hit the throttle at the worst moments like pulling out into traffic, and then not restart easily. The choke internal linkage seems to be missing something, as there is no high idle on cold choke and it floods regularly and runs rich most of the time. I've been through all the adjustment procedures to the best of my knowledge with the service manual several times, and still it sucks. Some times it runs fine, other times it surges badly, won't come down to idle speed, stalls, coughs and sputters, etc. I'm usually confident that I can fix anything, but this thing has a mind of its own.

        Where would one find the good late model version, new or rebuilt?

          Will ones from the earlier Champion flatheads work/fit? The 47-52 models are very reliable and so are the 53-57 models.

            Get a professional rebuild from Dave Thibeault.

              First you need a "Good" Carb. before spending money rebuilding junk. The Model and Sub. Model Number was on the Brass tag under one of the Top Airhorn screws.
              Best plan is find the number in the Catalog for the '62, put out a Wanted Ad THEN move forward with that.

                Rich, is the 62 carburetor better than the 61?

                  Have you given any thought to fuel injection? seems like you have had a lot of carb - fuel tank - line issues. Do you live in a high altitude area? I know a lot of jeep guys are using small throttle body efi set ups. A quick search showed Hamilton fuel injection, Does anyone have experience with them? They list Studebaker as one of there applications.

                    I am sure the '61 and '62 are both better than the '59-'60, just don't think it matters which version as long as it is Post 1960.

                    I always go with the latest and greatest year I can find of ANY Studebaker Part that FITS my application!

                    Here is what Carter Carbs. you are looking for:

                    '61S 1551523 = AS-3159S -exc. Y1 less governor *

                    '61S 1551522 = AS-3161S -exc. Y1 less governor #

                    '62S 1551174 = AS-3370S -exc. Y1 less governor *

                    '62S 1555176 = AS-3372S -exc. Y1 less governor #

                    '61-'64S 1552433 = AS-3372S - Y1 less governor # (Taxi)

                    (*) = Without PCV System

                    (#) = With PCV System (= With provision for PCV Valve & hose in lower mounting Base)

                        I'd love to go this route, but this is a low-buck car for now. It is my son's first car, and we just need it to be a reliable daily for running back and forth to high school and summer job, all within a 15 mile radius. At some point, it may get replaced with a rig that is more winter friendly, so I don't want to spend $$$ on major conversions. In the mean time, the car is a treat to run around town with, when it is working... It has become a bit of a joke with Ben's friends, because he winds up walking about as far as he drives it...

                            I wish I could say something more positive. All I can say is that my experience with carburetor rebuilders is even worse than with generator/starter rebuilders.

                            Every "professionally" rebuilt carburetor I have installed needed to be returned, or gone over again to some extent by me, before it would work. Maybe the folks buying these rebuilts were patronizing schlock shops, but these were old time shops in big cities. Everyone expected them to be good.

                            You have to start with a carburetor that is not worn out first.

                            Everyone seems to be happy with Dave Thibeault's work.

                              Good Grief No! That is the carburetor that people REPLACE with the AS model.
