Carter Yf Metering Rod/running Rough

The plow jeep is running on 2 cylinders at the moment(barely). I get about 1/2 cup of fuel at the carb in about 15 seconds so should be good on that end. 1 and 4 are dead but good compression. Popped the cover of the yf and noticed the metering rod is moving but not squirting anything into the carb. Its not engaging the pump. When i push on the pump it will squirt gas into the throttle opening. Out of adjustment? Anyone see something I'm missing? Been awhile since i messed with the yf.



I should add that plugs, wires, points, condenser, cap and rotor are all new with no change. I do get spark on all 4

 

How is the pump actuated. Shouldnt the metering lever, whatever supposed to push it down or is something else supposed to depress it?
As far as the weight, ??

It may have. Wondered about that but wasnt sure what to look for.

I know these are simple, just used to the 2g now.

 

I see what you mean by the checkball and weight. those are free. If i push down on the plunger-in the video the accelerator pump does give a shot of fuel like its supposed to.

 

Huh. Think im missing the choke connecting rod.


So vacuum is what moves the accel pump.

I pulled the carb and blew out and chased the passeges with a wire. Think one was plugged a little.
The accel pump does work so diaphram is good.
I might have an old parts carb from when i had wimpy. Hopefully i can find a choke linkage

 

But the choke linkage shouldnt matter too much with the manual choke cable on. Should just hold the throttle open a little more with choke on, right?

 

I guess thats what im trying to figure out. Looks like vacuum helps actuate the accel pump under load, but it should give a squirt of gas when you push on the throttle. Im not getting that at the moment. What mechanically actuates the accel pump?

 

Nothing other than the springs. I think by following the procedure for adjusting the metering rod and actuating the throttle by hand it's easier to understand what happens.

 

Never thought about it but that makes sense.

 

Ill have to look thru the manual again and check the adjustment.

Dont really want to have someone crank and me look down throttle to see if fuel is coming out. Waiting for a good backfire while i do that

 

Try this. At the high rev that was pedal to the floor. Almost at the end where it was "idling" i still had my foot on to keep it running.

Any ideas where to start?
Timimg? Fuel?

 

At first it sounded like the timing was severely retarded, but then it sounded like it ran out of fuel?

 

It is running on only 3 for sure and at times only 2. Sounded worse when i started it.
New plugs wires cap rotor...
Made no difference
Compression is good so valves should be adjusted good enough?i will have to put the engine at tdc and check the timing. Wire on rotor looks to be more at 6 o'clock position than 5 that the manual calls for

 

What did the exhaust look like?
