I'm not sure how it would effect the engine temp. Is this the car that does not have an electric fan on the radiator? What temp is it running at?
Since it seems that the fuel needle valve is not working then you are probably flooding the engine when starting wether hot or cold. The 72's have these little balls in them that fall out chances are that only one has fallen out but you might as wel do each carb. I think you have to get the ze-28k in order to replace the fuel needle valves. Each kit comes with several variances on the gaskets for the carb so you won't use everything in the kit. There are a few other gaskets that are convienent to replace.
Bascially you unscrew all the bolts from the top including the one in the center where the air cleaner screws. If you can't pull the top off then you gently pry with a small screwdriver between the two barrels be sure not to mar the surfaces.
From here there are two screws holding the fuel bowl down.
Once you have removed it you can replace the fuel needle valve.
Before reassembling clean all the old gasket off using a plastic or wood scraper. You may wish to clean the carb with carb cleaner before starting and then scrub each part and spary it with more cleaner. Be sure to do this outside and preferably with a light duty face mask. If you can you should spray the parts and then leave the area until the air clears.
Do each carb one at a time and put the rebuilt carb back on the manifold if you renew the exhaust manifold gaskets which is also a good idea.
Check how the car runs.
Then do the next one.
Once you have both rebuilt then make sure that the automatic choke covers are set 5mm past the rich mark. 5mm is basically just where the notch on the cover will go out of view as you turn the cover clockwise.
Then adjust the idle speed .. if you have problems gettin gthem to sync I have found that the adjustments screws get out of whack and need to taken off and adjusted so that both are at their maximum and then you can adjustment them down and you will have a better range of adjustment.
