Tim, I always have put teh standard engine oil in teh dampers. This was what
the garage always recommended when I had Triumphs in the UK. Also it is what is
listed in the manuals. It always has worked fine for me, so when I got the
current car that's what I have and it's no problem. Most of the cars I looked
at never had any oil in the dampers and the owners nver new to fill them. It's
one of teh first things I always checked. It showed if the PO's knew anything
about the car or not.
Also a thought about the Colourtune, did you do both pairs of cylinders?
Alan.

Richard,
Thanks for all the suggestions, I was just coming to the conclusion that maybe I
should get the car tuned properly. The only trouble being finding a mechanic I
can
trust, and who can still remember how to tune twin SUs. I have only recently
installed a fuel filter after a long lay up due to restoration, it could be that
it has pciked up rubish (ie dust from the kilos of bondo I gound out). Fuel pump
is new (100 miles) so that should be OK. I agree that fuel blockage should
produce
later sputtering. I ave put standard engine oil in the carb dampers, would that
be
a problem? I did this for many years in an old rover metro which had a single SU
and it was fine... The strange thing is the fact that it seems to happen as the
car gets hotter, so perhaps a vapor lock?
As to the temperature guage I'll try a thermometer, but where do you put it?
Thanks for the help
Cheers
Tim
