    Started working on my Blazer again after sitting for about a year and half. The fuel system is trashed. Good California gas has taken it's toll on the rubber lines and carb:doah: . I've replaced all the lines, but the carb bowl refuse to stay full after sitting for about a week. The Carb is about 5 years old, I spent big money on it, and it works great when it's running. What could it be leaking from. I am not a carb expert, thats why I bought a new one. Any Ideas?:confused: It's a stock Q-jet on a 1985 Blazer

    There are 2 plugs on the bottom of the float bowl. It is common for them to leak. Pull the carb off the manifold and turn it over. You will see the plugs on the bottom of the bowl. Just put some epoxy in them. It usually seals them up.

    Very common on a Q-Jet. Rebuild it and use a little JB Weld to seal it up

    I was just living with this problem. Leaks down overnight. first startup is always a minute of cranking. Now I have something else to fix.
