[Spits] a surprising fit for the throttle

[Spitfire4]

if you install the cable make sure you set the stop bolt so when you put your foot into it you dont rip the end off the cable...
a lesson I learned at a AutoX

I drove an hour home with only an High idle.
I did get some funny looks at stop lights

In the long run, it would probably be best to fit a cable linkage from a
late Spit and get rid of the mechanical linkage.  It makes the throttle much
more precise and lasts a whole lot longer.

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.
