I have to rebuild the carbs and replace timing belts on a 1978 308GTS. I do not yet have a shop manual but need to quote a guy a rate for the work. Does the Crank pulley and harmonic balancer have to come off to replace the timing belt(s) . And any tips on the Carbs, pitfalls or things to be careful not to do. I saw the timing belt thread. This car has never had the Timing belts replaced in its life so far. I think he has been on borrowed time for years even though the car has just over 7,000 original miles. I am asking since the manual is not in my possesion yet and I have never seen a blown up diagram of the timng belt layout. And I need to quote a price for labor , he knows parts will be at cost additionally.
