Sporadic idle after washing and timing my engine.

[crm318]

Yesterday before work, I decided to give my engine bay a wash down with degreaser and water. I made sure not to get any down the carb and as little as possible on the distributor. I also set my initial timing from 14 to 16 degrees. When I headed of to work ( a delivery job), I noticed that the truck had a low idle and that the rpms/tach would bounce every 5 seconds or so. It sounded like an intake leak. I made sure that all of the vacuum and electrical lines were secure and I set my timing back to 14. I also sprayed carb cleaner all around the carb to find leaks. I delivered for four hours last night and the problem was always present (any water in the distributor should have burned off). What do yall think?
