I have a 7.4 Bravo II w/ an edelbrock (carter/webber) carburator. I have never had to go to neutral and pump the throttle before starting. Even when starting it the 1st time in the spring. It does smoke slightly until the choke turns off and engine is warm but it runs good with no chugging or loading up.
Now my 1979 chevy blazer w/ a 600 holly carb you had to pump the living hell out of it if it sat more than a day. Does this seem abnormal to anyone?

Thanks Steve

is it abnormal that you do not have to pump it? Not with a webber, they leak fuel into the manifold. Holly's don't, and thats why you have to pump it.
with any carb, the standard starting procedure is to typically pump it twice and then hold the throttle 1/4 to 1/2 open, then turn the key.

sounds like your blazer needs attention and you need to learn how to properly start your boat.
starting cold at a dead idle can lean to a lean backfire. that lean backfire can not only stall the engine but actually force water into a cylinder.
trust me I dewater at least one hydrolocked motor every month or so.
when starting a carburated motor cold you want it to start and run between 1000 and 1500 RPM to insure proper operation.
most folks are so used to modern EFI they forgot about carburated engines.

And after 3-4 minutes pull it back to idle. Let it idle should be between 650-700.

Don't want to shift at more rpm.
