Mercury dies if I don't feather gas pedal.

[Guest jumpinjivinjoe]

I have a 1957 mercury monterey. It will get lower and lower rpms intill it dies if I don't feather the gas pedal. I just put a couple gallons of gas in the tank. And I recently rebuilt the carburetor. Any ideas as to why it does this? Thanks in advance.

Have you tried adjusting the mixture and idle?

I am also assuming that you are talking about the car after iut is fully warmed up.

I think the idle speed is alright. Which could cause my problem: too lean or too rich?

It would be rich ..when it dies do you smell gas and can you see it on the intake if it's doing that then it's your floats are to high, hope this helps you out.

I adjusted the idle mixture screws. They were at 2 full turns out. And now they are at 1 full turn out. As far as I can see that fixed my problem. Thanks greatly.
