Carb question, need to dump little gas in carb just to get car started Options

[angerosa]

Seems that this year I need to put a little gas into the carb to get the car started initially. I have single Solex carb that no one seems to be able to identify. I'm sure some PO just pulled it off something that was sitting in a junkyard. Once I get car started and it warms up it idles OK but runs rough when you try to drive it. Timing is spot on. Recent (not too many miles ago) tune up with the help of some very knowledgeable 914world brethren. Let’s say it’s a given that there is nothing wrong with the engine. I have an idea of where to go next. I’ve had car for about 7 years. With only what I’ve told you here what’s your opinion?

So everyone is pointing out this distance that just shouldn't be here. Looks like it's been like this for a while. I found two other Accelerator pumps in a bag of old stuff from the PO. Both were used and looked exactly the same as the one that's in the carb.

So we all agree this gap is too big. The only adjustment is the fine adjustment screw you see in the picture and it can't be screwed in anymore than it already is. Obviously the person who last rebuilt the carb turned the screw in as far as it can go. Nothing is broken or bent.

I also took a good look at the carb tonight turning the throttle and watching how the cam interacted with the accelerator pump actuating arm at different points. There's actually two lobes, first lobe sprays more when engaging the primary and the second lobe sprays when the secondary is engaged.

So I can think of only two other logical conclusions.
1. The pump is so torn that the button is pushed in farther than it should be.
or
2. The answer I'm hoping is the silver bullet I've been looking for.

Anyone?
