hard start when hot



I've seen this problem before. One car I remember was a co workers 68 Dodge Monaco Wagon that would do that. I would describe it more as hard cranking then hard starting.. Occasionally when trying to start hot, it would slooowly crank until the battery seemed about dead. Letting the car cool for 15-20 minutes & it would start right up again.

If your hard starting when hot is indeed caused by fuel vapor it is PROBABLY caused by fuel expanding in the carb bowl when the carb soaks the engine heat after you stop.  The fuel can expand and overflow the bowl and run down into the engine flooding it.  Lowering the fuel level by adjusting the float can solve this and has on several of my Mopars including a 54, 64, and two 73's.

I was just reading Jason's problem with hard start on his '68. I have never had a hard start with a 12 volt Chrysler engine but often have with my six volt  55 Hemi. I have found that making sure the connections are dry and tight helps, but believe there is a heat soak vapor lock problem also. The engine turns slower when hot, which might indicate cylinders full of gas vapor. Some of this gas may leak down into the cylinders while the engine is off. I have thought of a six volt electric pump, but feel since the car started fine when new, I shouldn't need it if everything is right.
 
Does any other six volt Imp owner have this problem? Has anyone replaced the manifold to carb gasket to solve it?  Who sells the gaskets?? Is this a good idea or am I looking at a carb rebuild? Like Jason's, mine starts well when cold.
