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?

Take off the screws holding in the accelerator pump diaphram, the housing around where that punger screw sticks out. Should be four screws. Behind it will be the diaphram, peel it off around the edges, carefully so you don't tear it. Below the diaphram will be the spring that it pushes against, that returns it to the pump position. I'm betting it's that spring, only think I can think of to explain that gap in the outside in the linkage, but look to see. And look closely at the diaphram, when they wear out there's a hole in a line that usually looks like it's been abraded. All easy to take apart, easy to put back together, and will be replaced when your carb kit arrives anyway. So no real reason other than curiousity.

The only other thing I can think of to explain that gap is that there was a cap on the plunger, where it sticks out, that's come off. Can't really tell, is that plunger plastic? If so it probalby had a cap where that screw contacted it. Any wear there on the plastic part, if it's plastic? If not that's another inication there was a metal cap that's not there any more.

(IMG:style_emoticons/default/agree.gif) Pull the accelerator pump cover off so we can see what we're dealing with. If diaphragm has deteriorated, or the spring has collapsed, it isn't functioning at all anyways. As DB said, if you'll be getting the kit in before this weekend, you'll be able to replace the diaphragm and reinstall the carb to get you where you're going.

Then you can pull it back off when you have the time to do the rest of the carb. If the rubber in the diaphragm is gone, it's likely that other o-rings and gaskets are on their way out soon too.
