I have a puzzling problem with one of my AD41B engines. It starts well and runs great. If I shut it off and try to restart it right away, it starts. But one hour later, it won't start until it cools down completely. The next morning, it starts fine. I've changed all the filters to no avail. There is no air in the fuel return line, but I have been able to restart it hot by disconnecting that. The problem persists whether I use the forward or the rear fuel tanks, so I don't think it's a fuel vent or a fuel pickup issue. Any ideas for further ideas for diagnosis of this issue would be very welcome. Thanks.
