I have a 1989 Force 9.9. The model is #92F9A, and the serial number is #1165. It would run for a while and then foul the plugs and won't restart. I rebuilt the carb., and replaced the original membrane in the fuel pump. Now I can't get it to run. It seems to have good spark and compression, so it seems to be a fuel problem, but I am out of ideas. Any help would be appreciated?? Thanks!!
