The 1910's were pretty rich everyplace right out of the box.  Most will have a very "fat" idle circuit, so not sure why you would need even more idle fuel from one unless it has a HUGE camshaft in the big 455 and low compression.

A stock 1910 more times than not needs leaned up a idle, not fattened up.

Edelbrock did use at least 4 different calibrations in those carbs from what I've seen.  They also had fundamental issues with them and machining errors, so difficult to say exactly what's going on without seeing it......Cliff
