4350 Choke pull off
The hot air choke is working great thanks to fmc400 and Number Dummy 
and I am finally getting around to installing the choke pull off which was missing when I got the truck. The exploded diagram in the ford manual show a "filter cap" on the end of the pulloff but this did not come with the new pulloff and I can't find one listed at the usual parts stores. My question is what exactly does this look like? maybe it would be in a rebuild kit? and what does it do? will the pulloff operate without it or will there be a vac leak?
Any thoughts appreciated............

Well as you guys probably already know can't get the choke pull off into the linkage with removing most or all of the carb at least I could not find a way. I did learn that it used to be much easier to crawl up in an engine bay that it is now ! So I am going for a complete rebuild probably next weekend.......I have fmc400's notes on the topic in front of me and hopefully it will go well if not I know FTE will help me through it! I could still use and answer to my initial question if anybody has the answer.

I apologize but I have not seen that before. Does your new pulloff seem to have a place for it? I'm not as familiar with that carburetor, but typically all the pulloff needs is a vacuum source so that it can slightly actuate the choke when the engine is running. Does that seem to be the case here?
As a side note, it's not uncommon for items shown in a rebuild diagram to be obsolete or done away with as modern replacement parts can consolidate multiple pieces, etc. Or, some items shown in a rebuild diagram may only apply to a specific and less common application that wouldn't have been installed originally.

Thanks for the input, the pull off does have a vacuum source and a hex adjusting screw? also there is a tiny hole in the end of the pull off itself but does not really look like anything would fit over. Your idea of a modified part makes a lot of sense. Here is a pic of the pull off. just FYI the carb tag is #D8TE AMA
It may be a case of "if its not broke don't fix it" yesterday while investigating the pull off linkage I made an adjustment to the ckoke and this morning it started on the first touch..of course it's already about 80 degrees here in SD! I will get a drive in later and see how far the plate opens after it is warmed up if it opens fully I will run it for a week and see how it does. Eventually I will install the carb kit and at that time the pull off, it seems to be a great system when all of the pieces are in place. But I might just drive it the rest of the summer and save that work for winter!
Thanks again for all the help.
