Several things of some importance I have not seen, or am I missing them.

1. Auto or manual transmission?
2. Current idle speed?
3. Current vacuum reading at idle?
4. Does car have AC
5. Any other conditions causing rough idle,,,carb issue(running rich or lean)spark plug/wire misfiring, Vacuum leaks, etc.
6. Current timing initial advance?
7. Solid or hydraulic lifters,,,I got the roller part.
8. What is meant by rough idle,,,there are different types. Hurky/jerky, lopping like big rpm swings or sense that engine is searching or wants to die,,,etc.
