Pdsit Choke shaft end piece.. wierd issue

[krisbeetle]

So I was going to adjust choke on one of the carbs on my 78, 1800.

I went to turn counter clockwise to wind the choke flap shut.. however I found that the end piece where the spring pulls against .... was free spinning.

I checked the other carb and it appears as though it is a hard connection.

Looking on the carb manual on here it appears to be one piece.

I'm not as familiar with these carbs... but is this end piece just pressed on? Or a key way or? It moves independantly on mine it seems...

Anyone else experience this/ have to fix this?

on most chokes the center is anchored into a pin with a slot in the center of the choke, and the other end wraps around the lever that moves the choke butterfly. If either attachment point is damaged, or the coiled spring has slipped off it will spin.

The one on the good side doesn't look keyed that way... more oval... or just round...

Its #21

Doesn't really show it how its round...

I feel like there is something else that should be securing it and its unlikely that it had worn the way it appears that it has...

Anyone who has taken choke apart before?

if the rod #21 works right then make sure that the choke spring is good because it engages that rod like the photo I linked. I have seen hundreds of chokes on solex and other carbs.

Right, understood Kent. Just to be clear what is going on:

When I grab that end piece with my hand in your photo that is supposed to be solidly mounted (the piece that the spring hooks against) and when I grab the choke butterfly with my other hand I can move these 2 pieces (that i think should be one as indicated by part #21) independantly from each other.

I took off the other side carb choke spring and it confirmed my assumption as that piece is solidly mounted to butterfly... unlike the trouble side carb choke shaft.

I just can't believe this part would be stripped... there is no way it would get enough torque....

The diagram I found does not show all the pieces... as another piece sits in behind the piece that the spring grabs and sitting in between them what appears to be a round brass bushing.

Any more accurate diagrams?
I'll see if I can take pics

the choke butterflies are solidly connected to the choke butterfly shaft. There is a second lever in the photo which is inboard of the main choke lever, and it is usually called an unloader. Its purpose is to open the choke when a greater load is applied. I think Bentley shows all these parts and adjustments clearly. MAke a video and post it if you can't figure it out.
