Feedback carb adjustment problems
I own an 83 ranger with a 2.3 liter motor. The old carb went south about 6 months ago, and I replaced it with a remanufactered carb. The old carb worked great until the lower section of the body wore out and could no longer keep the lower flap aligned right.
The new carb floods the cylinders if the truck doesn't start on the first try and diesels about 60% of the time when I shut off the key. My timing is where it should be, the mixture screw is adjusted correctly, and the idle speeds are where the VECI label tells me they should be. There are new plugs, wires, cap+roter and the coil is within limits.
My Haynes book shows the bowl vent lever setting and am thinking that this is out of adjustment. A Chilton book lists an incorrectly adjusted float as a possible cause for flooding. How do you adjust the bowl vent lever? How do I go about seeing if the float is set correctly? Will getting the Bowl vent lever adjusted alieviate my dieseling/flooding problems.
These Feedback Carbs are a real pain in the butt. Any/ all help is appreciated.
thanks

Welcome to FTE 83Rangerman,
Does this carb look exactally like the old one? How new is this replacement carb? Call the place that you got it from + bring it back! I've had them come right out of the box and not be right. I've had the same problems that you are having on another vehicle that i've owned ! It does sound like a float adjustment problem.

It looks exactly like the one it replaced, model number, castings, and the whole thing.
Since, judging by the limited consensus, it is a float problem. How do I adjust the float in a Carter-Weber feedback carb? How do I adjust the "bowl vent lever" ? Since that must have something to do with the float level, I'm thinking that is out adjustment. The Haynes book has a terrible picture and it is very difficult to figure out where to set the fork based on that illustration.
The other didn't have any problems until the bottom screws worked loose. I then cleaned the carb and rebuilt only to find that bushings on the bottom choke flap were shot.
As always, All help is appreciated.

This would probably be a good time to invest $15 on a Haynes service manual. It appears that you would rather not take it back to the place you bought it from. Don't they do service and installation?

Tonight I'm going to see if my warrantee is going to allow me to do a one-for-one replacement, Give that the carb is 6 mos old, It should be good.
If not, I'm going to put money into a rebuild kit. I spoke to a mechanic, and he said that maybe the truck's brain is registering some error and to disconnect the battery negative terminal, hook it back up again and keep the truck running at a give rpm, to tell the brain that everything is okay and to keep the settings.
Feedback carbs are a REAL pain.

I already have the Haynes manuel. The motor put in the mechanic leaked oil like a sive. I concluded that the rear oil seal was gone. The Haynes book only covered the 1-piece seal used most of the years. Early 83's had a two piece oil seal that fits under the rear bearing cap. The haynes book made no mention of how to replace the two piece seal and from their point of view never existed.
The book deosn't have good information for the carbs either. In the fuel section, they only say that Ford changed carbs so often that they won't discuss them. In the tune up section, there are a couple pages devoted to tuning the carbs, but the diagrams are somewhat confusing.
That book is barely worth the $15.
