Hi All,
Another hard-to-diagnose problem has raised it's ugly head. I have
a
'71 TR6 with stock Stromberg's. The car starts OK with the choke,
but
will stall if I don't keep gas on it. After about a minute, the
idle
starts to pick up and will go all the way to 1400-1500rpm's. One
problem is that I can't get the idle down - the idle screws are
backed
out all the way and are not even a factor. When I shut it off, I
get
dieseling (I use 93 octane and heat range 12 plugs).
Another weird thing is that it did this with two totally different
Stromberg carburators. All were rebuilt. The distributor is
somewhat
advanced, but I tried a number of settings from way retard to way
advanced. Fuel pressure is about 3psi and manifold pressure is 18.
I
have a sport coil with elec. Ignition.
I changed the distributor when I found that the old one had a
non-functioning vacuum retard and "frozen" weights and springs. I
found
one that had a good vacuum retard and loose weights and springs -
but
that is when all of this weird stuff started happening. Can it be
distributor related? When running, the car runs great. Strong pull
and
smooth acceleration. Any suggestions/ideas would be appreciated.
