Took some pics yesterday, figured I'd share! Ain't much to look at but it's on the road! 

 

And I think I too am suffering from the vapor lock. Runs great for a while, half hour or so, shut it off, restarts rough, and lurches and chugs the whole way home. 

Going to install a 6v fuel pump, eliminate the mechanical one, and re route fuel lines further from the engine. Might stick wooden clothespins on for good luck lol

Looks good! You did not oil it yet, did you? ?

For the vapor problem, have you already confirmed that it runs well with a little starting fluid?

Yeah I hit it with some sanding blocks to knock off the scaly rust and applied linseed oil thinned with mineral spirits.  Really added depth to the faded pale paint. I'm going to wash it again this week and re oil. Waiting on replacement drivers window. I took out the passenger and a local glass shop is making it from ¼laminate for $65

 

 

If it is indeed vl, my brothers thought was that once started, albeit roughly, and driven, the cool gas and air movement would cool the parts and return to normal running. 

We also found a broken wire in the distributor... no spark yesterday, replaced the wire. It could have been shorting or having poor contact causing chugging. More testing is needed.

If all else fails, check the choke, too, if your car still has the Sisson automatic choke.  A treatise on how to service and adjust it was posted a few weeks ago.  If it's not working correctly, it can cause starting problems and rough running when the car is hot.

It does not. We put on a manual choke cable. 

Also doesn't have stock carb. Has a Stromberg BXVD3.

Check the base of the carb, is it wet?  If so rather than vapor lock, you might be suffering from percolation.   This is a rich state caused by improper float level, high under hood Temps expand the fuel in bowl.  It overflows raw fuel into the manifold where it puddles, causing a flooded condition.  Check your float level and needle and seat.  Today's gas expands at a lower temp than old real gas, set your float a Couple 32's less than factory.  Next time you encounter this situation,  slowly press and hold wide open throttle  before you crank the starter.  This should clear any flooding if it's a percolation problem.

Yes! The other day we chugged it home and the gaskets were wet with fuel!

[greg g]

The other thing to check is the heat riser flap on the exhaust manifold.  If it is there  and you can move it, twist it fully clockwise and secure it.  This is the summer position.  3rd, invest a few bucks in a phenolic spacer to go between the carb and manifold.  1 inch thick will do you.  You may need longer studs and another carb base gasket.  Make sure the gasket for the carb base has the slot to feed vacuum to the small hole in the carb bottom.  

 

Langdons Stovebolt web site had the spacers, but I thought I read somewhere the business closed.

Their definitely is something to be said for the patina of an old car not repainted.

You can just see years on the car from another era. I like mine the way it looks when I bought it, but it's too tempting to put it back in factory paint. I was thinking about a semi-gloss just to cut the sheen. Maybe that's a bit silly. But I really like your car!
