Motorcraft 2150 Carb Upgrade
« on: July 07, 2011, 12:41:28 AM »
On the 4th, I finally got around to opening up the box containing my upgrade kit and starting the process of replacing my old carter carb. Today, I made it to the part of the process where I got the engine started and now I'm working on cleaning up the engine bay and taking care of all outstanding issues with the install.

First impressions:

  • At most rpms, the engine runs much quieter than before
  • I get consistent acceleration through 75mph. Before, I'd really have to strain above 55.
  • I still have a stall issue that requires higher than normal idle, but now that is 1500rpm vs 2200rpm*
  • The biggest thing is just how smooth it all sounds and feels.

*There was a brief (20 minute test drive) where the idle was set normally and I didn't have the stall issue. I'm relatively confident that once I deal with the outstanding vacuum hoses and wire in the choke, I should have a normal idle (and even quieter car).

The ECM had been bypassed for the past two years.

I forgot to mention - I now have an instant startup. As in get in the car, turn the key for barely a second and the engine is up and running. This is a big change from having to crank and pump the gas for about 15-30 seconds before it would fire up.

Did you fix the stalling issue?  If not, post some good pics.  It is most likley vacuum or timing.

I have a 2150 knockoff clone on my 83 wagon.  It runs great, if clean.  Was chasing a constant stall-when-coming-to-a-stop issue after engine was removed to fix a rear oil seal leak.  The emissions twin hoses from the air cleaner housing were left off and dirt got sucked into intake of carb. 

Totally felt like a vac leak issue, and spent much time chasing this problem, only to come to conclusion that vac lines were ok.  Had to screw idle all the way up, just to keep it barely running, unless I kept foot on accelerator, just to keep it going.  Ran fine once main jets activated.  So, I took carb cleaner, and with attached straw, put the tip firmly on the two vertical brass tubes in the carb throat(the ones as thin as a fat pencil lead), and also the two screw threaded tubes between them and venturi throat, and blasted them in an alternating pattern, until I saw a little speck of gunk shoot out.  Immediately after this blow out, engine runs as smooth as a rolls royce!  Rpm immediately was way high at idle, so cranked idle speed screw back down, and like a new engine.

I had the same problem. Bought this rebuild kit.

Runs worlds better. Need to fix the rear brake problem, ( broken brake shoe ) then get it inspected so I can actually drive it and test out the rebuilt carburetor. The add states it is designed for todays volatile fuels. I hope they are taking about ethanol.
