I checked the timing before changing anything and it read 16 to 17 degrees btdc. I retarded it to about 12 and turned up the idle a little. It seems to have a rougher idle at this point.
The vaccum is reading 9..........



Your vacuum is only 9" ???? At what RPM?

Thats really low for anything expecting to pass emissions. You might try setting the timing a little higher just to get some vacuum back. But again, What is the idle speed?
