Title: Edelbrock 1903 leaking. Please help
Post by: Dirk22 on September 08, 2014, 04:37:25 PM

I have a 1903 that is leaking from the driver side primaries. When idling I can see fuel dripping down on to primaries. truck runs really rich and also has a small whistle at idle. Any help would be great

Thanks
Dirk

 Welcome to CHP!

 Sounds like you have a worn primary throttle shaft and/or hole the shaft goes through. Which could be causing a fuel leak and the vacuum leak. Probably needs to be drilled out and rebushed. Also, it could use some tuning/adjusting, due to it running rich.

Incorrect gaskets will also cause that issue.  If it is dripping from the main boosters at idle speed, the idle tubes may be plugged as well, or not big enough for the application....Cliff
