Darcy,
I run a 2500 S saloon with twin HS6 SU's and I had one of my float bowls
custom modified so that the fuel supply was even to both carbs (due to the
fact that the motor is angled backward). I am not sure if the TR6 is the same
but I was told by an expert that issues were quite common with twin SU's on
the saloons due to the angle of the motor. I can try and get more info if you
want.

Subject: HS6's on TR6
I have been reading the list digests for a while now and hope I can get some
help on the conversion of my TR6 to HS6's. I got what I though were
appropriate items from Burlen Fuel Systems to convert the HS6's I got that
started out in a '77 TR7. This include the yellow springs, conversion kit
to
eliminate the waxstat jet, new spindle shafts and throttle plates w/o the
run-on valve, and a few sets of needle using the Moss Performance Tuning
manual as a guide for choices.
My problem, after the rebuild and getting the linkage right is that
performance is good up to 2500 rpm but after that I get terrible back
firing.
I'm running the BAE needles, fuel seems to sit low in the main jet in the
rear carb (1/4 inch below jet) but good in front carb. I also added Kerr
headers while I was working on the carbs. Any help would be appreciated.
