Default 4 hole 1/4" gasket.

Hi Matt, in http://community-2.webtv.net/MATTGRU/carb/ you suggested installing Felpro # 1905 for better mileage, well I just got the gasket. Is this just a matter of removing the Q-Jet, removing the old gasket and reinstalling the carb or is there anything else to it?
Thanks, Pete.

That's it. Don't expect dramatic gains. Maybe 1/2 mpg if you are lucky.

The old gasket had one big hole, now the 4 hole gasket matches the 4 hole intake manifold.
I'll post back if there is any improvement in mileage. Hoping for better than 1/2 MPG.

Lost the choke rod retaining clip in the process.

As an aside: the Auto-zone flare wrenches are junk, rounded off the fuel inlet connection.
