351m idle speed.
I got a 81 f250 with a C-6 auto and a 351m engine. Im wondering what the idle speed should be set to. It seems to be running a bit low. Thanks

The engine adjustment settings are on the emissions lable located on the radiator support.

Follow the directions for an automatic if it has both, manual and auto settings.
