1962 Buick Invicta - dont know why this happened
New to the classic car game. Have a 1962 Buick Invicta 401/445 Wildcat Nailhead. Purchased car from CT. I went up to CT saw the car and drove it. He did me a solid and drove it down to NY. Smelled gas and the fuel filter was leaking. Took it off and cleaned the rubber gasket. I was very careful not to drop the glass bowl. Than I look down on the floor and see this very thin gasket that seems to go on the center of the filter?? Maybe, dont really know. I only saw the main rubber gasket that goes on the housing between it and the glass filter. Is there a second smaller gasket? Maybe it was stuck up under the housing and fell after I took the filter off but I didnt see it. So I clean the glass, put the filter back, fill the filter back up 80/85 % with gas and replace. No leaks Great. Now the car runs like crap. Why? It races it knocks. It wont idle down. Did I some how trap air in the line. Can I bleed the system a little? What did I do wrong? It is a far cry from the way she pulled up in my driveway. This is only day 2. Here we go
Thanks for your help.
