94 502 running problem?????? help!!! pos vapor lock???
I just bought this boat with a blown motor. rebuilt it and ran it for about 10hr. runs great BUT!!!! it seem to have one problem, after you run it for a 1hr or so and stop, shut it off and let it set on a heat soak, sometimes it will not start back up. it acts like it is flooded out ! you have to hold the throttle wfo to get it to start . when it does start it dont black smoke, like it was flooded out or anything. but it will not idle at all ! now this dont happen all the time . just about 90% of the time and only when it is warm. it runs great when cold it runs great the rest of the time .

I had the same problem with my 93 502 MPI the diaphragm in the VST had a small hole in it and it would dump allot of fuel down the vent tube into intake runner #8. this caused a very hard start. Im not sure if the EFI has the same fuel delivery system thou.
