Many readers from this list responded to my query last month about "Vapor
Lock" so I thought I'd follow up:
Rather than vapor lock, or another fuel-line related problem, my mechanic
traced the problem to "points and condenser", which were replaced last
week. I ran the truck for the first time yesterday, and have to say, the
performance was the best it has been since I've had the truck. No
sputtering "backfire" while going down the hill from my house. Smooth
acceleration, and even a little more top-end than before (ran 50 - 55 mph
no prob).
However, I still suspect some fouling in the fuel line somewhere. Once, on
the way home, the truck just sputtered, but didn't stall. Then, coming
back UP the hill, it really sputtered, though again, didn't stall. What
could cause that, except maybe some crud coming up from the tank?
One other thing that is different now, the idle speed is much higher than
it was before. Don't have any kind of tachometer, so can't give you any
accurate figures, but I can tell from the sound that it is idling much
higher, even with the choke pushed all the way in (and the "throttle" knob
doesn't work at all). Would changing the points and condenser increase
the idle speed? I'll have to look at the manual when I get home tonight
and see which screw on the carburetor is the idle speed and see if I can
adjust it... but, basically, the thing ran so great over the weekend that
I'm reluctant to mess with success.
One other thing. I backed the truck into its usual parking place in my
driveway, and an hour or so later when I went to get something out of it, I
discovered that the right-rear tire had gone flat.
Like my friend "dorson" says, "with these old trucks, it's ALWAYS
something...."
