Hi again,
Yep - your right, Spitfire drivers are thickskinned - you have to be to get through a full winters 'top down' driving - Brrrr! :-)
Waxstat, hmm, (or Capstat) is a type of SU jet bearing that was developed to raise the jet (or lower it) dependant on the temperature of the
fuel passing through it. A temperature compensator if you will... the problem with them is on a hot sunny day the under bonnet temperatures can
get so hot the jet is 'leaned' off far too much and the engine will stop (or not re-start) - so most people convert them back to the standard
jet.
I think the real problem lies with 'old' jets and new ones are probably okay - otherwise they would never have used them.
You can easily tell if you have waxtats by looking at the jet assemblies (at the bottom of the carbs). If they are big and flat then you have
Waxstat, if small and slim (usually red) then you don't.
I think they were introduced for the Spitfire 1500 but weren't fitted to all.
