Motorcraft 2150 Carburetor
Replacing the plastic choke lever.
Some of the Motorcraft 2150 carburetors have a plastic choke lever that at 1st glance may look like they cannot be replaced. This lever on the Motorcraft 2100 and early 2150 carburetors were simple to replace.
Watch a video about replacing this lever on the 2100 carburetor.
The later Motorcraft 2150 carburetor is a bit more difficult, but it
Here is what we are talking about.
The brass shaft pokes through the brack that envelopes the plastic lever and instead of a clip securing the end of the shaft, the brass end is mushroomed out. IMPORTANT – mark the shaft and plastic
Remove the C clip as illustrated.
Notice the rectangular hole where the end of the brass shaft ends in the bracket. It may be hard to see, but the end of the brass shaft is cut so that it fits into the bracket and is stationary. There are two
ways you can approach this. One way would be to file the edges of th mushromed end until the shaft can be punched out of the bracket, leaving enough material to be mushromed back out after assembly. The 2nd way would be to grind the end flush, punch the shaft out, then drill & tap a small hole in the end of the shaft. Using a washer and a screw will hold this in place. This is the approach I took in this case. A #6 x 32 screw would work well in this case, or find a self tapping screw about that size.
Motorcraft 2150 Acceleration Problem
You press on the gas pedal and the engine seems to bog down. What to do?
1st let me say that there are issues besides the carburetor that can make this happen, but since I’m in the carburetor business, I will assume everything else has been taken care of and concentrate on the carburetor. Also I will assume the carburetor has been rebuilt. If not, then that is where I would start.
Most likely this problem lies in the accelerator circuit. Here are some things to look for.
After all of this is done add some mineral spirits to the float bowl and operate the accelerator pump. You should see fluid come up through the main discharge (where the check ball and weight is). Replace the venturi cluster and operate the pump again. You should get a fairly strong stream of fluid out of both sides of the venturi.
Do all as mentioned here and you should be able to eliminate your hesitation problem, or at least eliminate the accelerator pump circuit as the cause.
