I would say that the 1940 is most likely the correct carb for that year and engine. I believe Ford used that carb on the 144 and the 170 up until the mid late sixties(66-67). AT that time the Autolite 1100 became more common. Then came the YS/RBS era--I believe late 60's early 70's. This is generally what I've seen through the sixties. Mike
My Eco manual has Ford & Holley carbs but not the 1940. I'm having problems with it so if I replace it, I want to replace with the right one. Thanx Much!
According to my chilton manual the Holley 1904 carb was used. Must have the spark control valve for the load o matic dist. They made them both ways I believe.
The Holley 1940 is a service replacement carb, so the carb has been replaced at some point.
You can purchase a rebuilt replacement carburator at O'reilley's auto parts. Usually they're not that crazy expensive. You could also get a rebuild kit if you're so inclined. The 1940 may be a replacement for the 1904---I don't think there's much difference. Good luck Mike
I have the Ford shop manual(Didn't know about the Haynes). The exploded diagram of the Holley(no numbers) is not my carb. I will try to rebuild. Does not want to idle? Are there better carbs for the 144?
Not really. To get a better carb on you have to modify a later dsII dist to work in the 144 it can be done, but you're better off swapping the motor to a 200 unless you're really into having the 144. Some people love the autolite 1100, I'm not one of them, it's a crappy carb with inherit dead spots and hesitations and finding good cores is difficult and can be expensive. Imo, you're best to stick with the 1940 and give it a good rebuild, check out mikes carburetor parts, great guy to deal with and great info on the carbs and their specific quirks. http://www.carburetor-parts.com/Holley-1940_ep_343.html
OK, took the carb apart, cleaned, re-assembled. Put back on Eco. Same thing. Will not idle. Actually it will not run unless I keep pumping the pedal. Beginning to think that it is not the carb? There is a vacuum hose(?) attached to the side of the carb. Aren't vacuum hoses supposed to be air-tight? The fitting is attaching a copper tube to the carb but the tube is loose with no way of tightening. Rubber goes over the copper & goes over to the distributor. ????????
Spray some carburetor cleaner down into the carb and see if that makes the engine run better,,,,if it does, spray the outside to see if that makes it run better,,,,,,,disconnect and plug any vacuum lines coming off the carb,,,,,so that checks for vacuum leaks,,,,,,if no vacuum leaks, then problem is not enough fuel getting into the idle circuit,,,,,but do some tests,,,,,get us more clues......are the points and timing set correct?
