 The thermostat is a 195 degree version. The jets as far as I know are
 the original jets that the carb came with. I bought the car used so I
 have no idea. But needless to say they have been in there for over 20 years
 and probably need to be replaced. I do know that this car has roared
 and flew down the road with this carb in the past.

 I changed the plugs from Autolite 145's to Autolite 25's. I'm considering
 going with AC R43T's.
 The wiring is orginal and in some places looks horrible. I'm going to
 run some new wire to the coil and see what that does.
 Thank you for your help. :)
