Radiator, etc.

I have been spending some time removing miscellaneous parts - front bumper, seats, front carpet, glove box, and misc trim.  The rear sets are in great shape except for the very top of the seat back where the sun has faded it.  I'm going to see if I can get that one piece replaced as well as re-upholstering both front seats.
The next step will be to replace the radiator (just bought one on eBay) and get the engine running perfectly before moving on to the body work.  The car starts very easily and initially ran pretty good but is now not taking gas very well and the choke never seems to shut off.  The mechanic says that the timing belt is a little loose and should be tightened so that the water pump can pump properly and heat the water enough to turn the choke off...  Or something like that.
