motorcraft 5200 carburator

[buckspet]

has anyone tried to use a ford motorcraft model 5200 carb on a 79 124 2L? I believe it's a liscensed weber design 32/36, if so what linkage mods need to be done? how about jetting?. The carb was used on Ford 2.3L 4 cylinders. I happen to have a NOS unit I planned to use on a ford inline six, but decieded to go with a turbo and holley 4bbl. So it's just laying around, would love to repurpose It.

No idea on the linkage, likely you could use the kit that Mark sells? For jetting I would use what people use for the 32/36DFEV.
FWIW I think the jet numbers on the Holley do not correspond to the Weber numbering system, as one time I pulled out a 200-something main jet from a Holley. You may want to swap all the jets so you know what's in there.

thanks for the info...If this is a version of the weber 32/36 im surpised that others aren't using them they are available and crazy cheap!!! anyone else have any experience or insight?

throttle lever on the wrong side, choke connections require new hoses, air cleaner doesn't fit. Some people use them but they are more difficult to fit than the correct carburetor

I swapped one on on my '79, on an 1800 intake. The carb's application was a '73 Mercury Capri 2.0L automatic, to be very exact.

At first it had a bogging issue if i gave it a bit of throttle at cruise but WOT was very strong.

Once I tore into it and did some research on the Capri's stock jetting, I realized the jets/emulsion tubes were switched around between the primary and secondary. Fixed it and now it runs really really strong.

I also bought an electronic choke...IIRC one opens clockwise and the other counter. I don't remember which is which but a choke from a DFA or DGA will be correct depending which way it opens. That's difference between the two. The DFA and DGA are "mirrors" of really the same design that have linkage on opposite sides.

Now I'm a FI guy, but I don't have an AFR on the Fiat, so I'm not sure exactly where the stock jetting is vs. optimal, but I can tell you the Fiat must want darn close to what the 2.0L capri runs stock, and it runs WAYYYYY better than the stock '79 carb with no perceived driveability issues at all now.

Also for the linkage I used Empi 99007.116 but all you need is the ~ 1" piece with the two holes.

The stock '79 arm will fit with modification too but its a little thicker so the nut doesn't have much thread with that option so I felt better using the EMPI one which 2-3 MM thinner.

A carb jetted for the six will be IMHO too big. Go get one for the 73 Capri 2.0L. My reman was < $75.

Thanks for the input Blue... the unit i have has a electric choke so i'm guessing the idle selonoid wiring should be a direct cross over. I'm going to get that empi part you recommended. Do you remember who you ordered it from? Also I see with other weber carbs the forum talks about spacers under the carbs to get proper height. any comments on the height issue? Thanks for your input, I'm enthusiastic about using this alternative carb, simply because it was so inexpensive...after I get it going I hope to send pics to the forum so others can take advantage of the significant value and avaiability

Any progress?

Sorry I haven't been on much lately now that "car season" is coming to a close in WI.

I replaced the studs in the intake with about 3/4" shorter ones in lieu of running a big thick spacer (=expensive...i think they were like $50 ) or stacking a couple of the smaller ones. I have a single 7-10mm spacer in there and run the taller lunchbox air cleaner (3 or 4" IIRC.) No clearance issues w/ the hood. Checked it w/ some playdoh and had inches to spare.

Yes, the wire that was plugged into the old carb's idle solenoid can just go on the e-choke terminal on the new one -as plug and play as it gets.

I got my empi throttle kit either off ebay or amazon. If you google that part # you'll find it easily.

BTW I see comments that the throttle lever is on the wrong side on these. Its not, at least not the 73 carb as mounted on my 79 unless previous years were different. Secondaries point towards the motor. The linkage is on the firewall side, pulls the right way for the '79 linkage setup, and works w/ the '79's stock rod with only a minor modification: I had to tap an additional 1/4" of threads or so - easy peasy.

Also the '79 stock air cleaner has all that air injection stuff and my car is a 60+ degree car, so I didn't go that direction since I really don't need heat stove plumbing and all that, but it could easily be adapted to fit if you want to keep the heat stove.

Once thing I haven't done is rig up my crank breather. I saw where someone mounted it to a flat piece of metal against the air filter element, sandwiched between the top and bottom cover, so I"m going to try that first. Otherwise the crank breather on the empi air cleaner is small and restrictive - probably a bit too small. It does seem possible to go 1-2 sizes up though so I guess that would be plan B, with (distant) plan C being just using one of those dumb crank breathers from the parts store.

My current project is floor pans. They are worse than I thought. PO did a real good job of hiding his kludge of aluminum panels, roofing tar (messy pita to remove) and undercoating. Pass side isn't bad at all but drivers side is going to need some small custom patches to go along w/ a bigger section I'm replacing from a repop panel. Fun stuff.
