'73 starting problem
I have an L82 4 speed with 53K original miles. It runs great and fast. Here's my problem. After sitting all week in the garage, when I start it, it turns over strong, but does not "start" until 15 seconds of "cranking" pass by. The rest of the day, it fires up immediately. Original fuel pump, new fuel filter. Any thoughts? Thanks.

'73 starting problem
I tightened the 9 screws (in order according to the service manual) but the problem still persists. I see that there are two gaskets; one at the bottom of the carb (thick) and one about 2/3's up (thin). Are these the gaskets you are referring to?

Any suggestions on where to get one? The corvette parts places (Ecklers, Corvette Central, Corvette Ameraica, Stoudt) that I have looked at only offer the thick base gasket.

Where I got my rebuild kits. Very reasonable, Delco kits.

Do you give it a couple or sometimes three pumps of the throttle to give the engine a prime and set the choke?
Or are you attempting to start it like a fuel injected car and not touch the throttle at all?

The well plugs on the bottom of the carb are leaking slowly. This is a common problem with a Qjet. You are cranking and the fuel pump is filling the carb back up. Once it gets gas in it, you can drive. It will start right back up if you shut it off, right? You can live with it or tear the carb down and epoxy the bottom of the well plugs.

Thanks for all the replies. Mark (stingr69) described what was happening. Before I start it, I pump the accelerator 5 times. This does not seem to help as it still takes 15 seconds to finally fire up. I do not smell gas. I'll have to check the choke. It runs at 1700 RPM after it starts up and stays that way until I kick the accelerator, then it drops down to about 800.
I'll have to live with it until spring (upstate NY) then work on it.
