I noticed I've been going through a tank more quickly than normal lately, and popped the hood to see what I could find. I noticed I have a significant leak coming from the bottom end of my weber carb. Looks to be right at the accelerator pump. Hoping it's just that gasket. Here's a video for more clarity. Thoughts anyone?

 

Well, video isn't working right now, may get it loaded later. But it's a very consistent leak that drips a few drops of fuel every time I give it hard throttle. The accelerator pump arm is soaked by rev #5

The accelerator pump diaphragm may have ruptured.  Rebuild kits come with a new one.

Thanks for the response Ferox. Between a bad gasket or a rupture diaphragm is one more likely? Seems it might be worth buying a rebuild kit anyway at 24 bucks..

the diaphragm and gasket should all be one piece, if you have a DG/DF anyway.  And assuming were talking about the same thing.

Ah, yeah I don't know much about the internals of the weber. It's a 32/36 DGEV. I only call it a gasket because that's what it appears to be when looking at it from the outside.

So I'm looking at this kit right now http://www.webercarbsdirect.com/ProductDetails.asp?ProductCode=92.3237.05&CartID=2 . I'm also considering getting this cutoff solenoid http://www.webercarbsdirect.com/ProductDetails.asp?ProductCode=43914.060&CartID=1 I read that it replaces the primary jet, does anyone have a picture of how this looks? I can't seem to picture it in my head.

Does your engine 'diesel' when you shut off the ignition?  If not, don't buy the cut-off solenoid.

 

I had to look into my 'S' files ( Subaru, for the Weber drawing  ).  The idle cut-off solenoid replaces the Primary Idle Jet. It has to be connected to a keyed 12 volt supply.

 

I have a drawing on the Weber  32/36 DGEV / AV. The idle cut-off solenoid, #100, replaces #33, #34 and #35, the primary idle jet, o-ring and Idling jet holder respectively.

 

You may not have a drawing showing/listing part #100.  But you can see where it would go to replace the primary idle jet.

 

In summary, don't do it.

It used to diesel a lot, but I noticed it does it much less if I fill up with super unleaded or premium. I skipped the solenoid for that reason.

Perhaps a treatment with Sea Foam will help blow the carbon out.

I may do the sea foam treatment once the carb is fixed.

 

So now I have to decide if I'm going to take the carb off and replace all the new pieces I got in the kit, or just replace the AP diaphragm. The carb was installed new by the PO about 15000 miles ago, so I'm leaning towards just doing the diaphragm. Any suggestions?

nothings more likely to fail than when you have just F'd with it.  if its running good, do the diaphragm and save the kit for later.
