RE: [T3] Not starting after long drives

Just for interest I had a similar problem with a '65 non fuel injected. It
definitely seemed to be fuel starvation, caused by evaporation from the
carbs and siphoning out of the lines. I had already changed all the fuel
lines and I cured it by mounting an inline fuel filter vertically on the
engine compartment bulkhead, so that the fuel could not siphon back. This
helped a lot, although it still needed a bit of cranking to get fuel back in
the carbs, but at least it would start before the 6volt battery died. This
has worked fine now for several years.

I have had this problem and my 72 was the worst also. Russ might be onto
something with the Trigger points idea. Once I would clean the points the
problem seemed to get better, but you know how that is, sometimes wearing
blue makes problems go away ;)

I also have a similar but not the same problem on my 71, it does start it
just has a harder time when hot.  I did not have it that often with my 69,
but it had the bypass switch installed.

Funny thing is I don't know how much it has to do with heat.  Because often
I could drive very far, say a couple of hours and never run into the
problem.  I would only happen with short dirves for about 15- 20 min.

Even though installing the switch seems like a cop out, its better than
getting stuck sitting in frustration as the engine turns, draining the
battery until you are really stuck (ask me how I know :) I don't think there
is anything so frustrating as knowing you have done everything tune-up,
replaced the filter and hoses, checked all the wiring etc.  And still being
afraid to take your baby out for fear that it won't start for no apparent

Moral of the Story: wear your lucky color and install the switch.
