Well thanks to everyone that threw in their 2 cents to help my no start... my conclusion is low compression because of washed cylinders. I only got compression on 2 cylinders before my compression tester stopped holding pressure. Gonna see if replacing the Schrader valve in the tester. Plugs smelled fuel fouled this time when I pulled them out. I threw in the old plugs that I pulled out of the truck and it fired right up. So I reset my carb and got a new set of ACDelco's to put in. Had NGK's (Figured they were alright since its the only spark plug used in my SAAB), gonna swap them in once the truck cools down.
