I am running the Summit carburetor on my 292 these days, and in when there is considerable heat soak and triple digit weather I get a lean condition. I bought an idle feed restriction kit from Summit and upped my sizes from .046 to .052. It is always incredible how such a small .006 increase will make.

More of that in the video here the includes a test drive.
