My GT6 has always had an imprecise throttle. I partly blame a PO's
transplant of SU carbs whose mechanical arrangement may or may not be
appropriate. But partly it is because the big transverse shaft which
runs across the car from driver to carbs has fit only loosely in the
firewall hole on the right (carb) side. It has never had a real
bushing or grommet. I've ordered two from Spitbits hoping they would
be true bushings but their picture looks like a normal rubber grommet
and it is labelled grommet. Maybe that's all it is supposed to be;
I've never look carefully at another car's.
So today I was cleaning up some stuff left over from last week's
rainfest at CCBCC's British Legends show. On my workbench was a 1"
long discarded piece of gas line. The inner diameter looked to be
exactly the diameter of the throttle shaft. And the outer diameter
looked to match the hole in the firewall as near as I could actually
see it. Since I rarely have as much time to work as I did today, I
wondered if I could get this taken care of for the time being. What
the heck, let's see if it will fit...
Surprise, it fit exactly. It took no persuasion to slip over the end
of the shaft in the passenger's footwell and minimal persuasion to
get to through the firewall. Don't know how long it will last, but
it can't be much worse than a rubber gromet. It might have been made
for that application.
