Speed up kit...............Avanti

[Hawklover]

This concerns Studebaker Avantis with a/c.
If one looks at page 31 in the parts book, one sees listed a carb idle speed up kit, p/n 1563113. This is purportedly to increase idle speed when a/c cars slow down and come to a stop with auto trans cars.
Now later in 1964 Studebaker issued service letter dated April 24, 1964. This was to address overheating with Avantis with a/c, a special kit with the p/n 1563542. So my question is this, is 1563113 and 1563542 for all intents and purposes the same? Hopefully either Dwight or Brad can shed light on this issue.

I do Not see how a faster Idle to prevent stalling, would have Anything to do with improved Cooling. that could be something like a 7 Blade Fan, etc.

Rich both kits for all intents and purposes prevent or attempt to prevent engine stalling with cars with a/c. I looked at the parts breakdown, almost identical.
