My 84 240 dl runs well 99.9 % until that time when it starts ok and then 15 seconds later stops. Overtime I have found that no gas is getting to the carb. Took off the fuel hose to the carb and found no gas in the line. To get it going I shoot down some quick start and that seems to prime it and the engine works fine. I always seem to know when it fells because the engine runs very quiet with no pickup. Want to know if there are two fuel pumps with this vintage and are the fuses that are labeled in the fuse holder for the two pumps valid. I checked the tank from the trunk inside to see if there are any wires going in but can't see any. The hose going to the carb looks like its going to a small type pump on the side of the engine. Any thoughts, suggestions much appreciated.
