Been having a problem with it not idleing down, spent the weekend cleaning the carb, lubing linkage and cables etc. still wasen't working. So I pulled the accelerator pump out to find that the blue "washer / grommet" on the bottom of the shaft had disintigrated allowing gas to get on top of the pump "hydrolocking" the shaft down. Just an FYI incase anyone else is having a high idle problem (having to blip the throttle to get it to idle down).

Agent,
Did you just order the part from Edelbrock or do you have a homemade substitution? Mine is somewhat doing the same thing. Thanks, Tony

Tony - I called Edelbrock and was told that they don't sell parts retail, only to distributors, they gave me the phone number of a Harley parts store that stocks Edelbrock parts. Here is the website -
http://www.wallyscycleworld.com/. Placed the order yesterday, hopefully get it around the end of the week.
You will need the part numbers, here is the schematic and part #'s, thanks to Creeky for posting this a while back - http://www.edelbrock...b_internals.pdf

Krannie - if you look at the PDF file posted above - it's # 53 - part # 9098. On the bottom of the shaft is a blue rubber "washer" that's intrigal with the shaft.

Thanks for the PDF. I have been wondering what that 49 pump check ball does. I found it and the 50 needle when they fell out of my carb when cleaning. The needle I put back, but did not know where the ball went. I still cant tell from the pdf. The carb is running well without it. Anyone know what it does, and where it goes?

After reasembling my carb I had that funny feeling that maybe I had lost that check ball, but after pulling the accelerator pump I noticed it in place at the bottom of the pump well.

Funny thing is I have never pulled the pump assembly. I wanted to, but it did not want to come out and I did not want to F something up. Interesting.
