"under hood temps are extremley high"
Hi-Jacking this thread for a moment, Bill, while running with those high temps, do you experience any perculating/vapor locking problems? I fought mine all through August out here when outside temps were over 100. I replaced everything from gas cap to intake manifold with new including tank, filter, elec pump, fuel line, carb (Edel 600), 2" phonelic carb spacer and the problem finally left after the hottest weather left!
(292 with LPG pistons, AFCO alum rad, A/C, no hills or trailers!)

I have a water heated Offy with hot water routed from block drain thru manifold heat plate to waterpump with small bypass neck. A temporary clamp had no effect on the stalling. The engine will start right up after getting stopped and into 'Park' and will run for a block or 2 and sometimes half a mile. I was getting ready to add a switch ckt so I could kill the fuel pump at first sputter and then check for low/no fuel in carb when the problem seemed to 'evaporate' and now it will take WOT for as long as I dare hold it down (speed limit ya know!).
While there's not much I can fix now without a malfuncion, I guess I'm hoping to collect some tips and tricks to get ready for next summer!
