We just bought a  1974 260z with triple carbs.  However, they are locked up and unusable.  Is there a solution to unlocking them?  Also, if we have to replace them, what is the difference in the Weber triple carb and Mikuna triple carb?

 

have a picture? if it is the carbs that are seized up, you could soak them in carb cleaner or paint thinner for a few days and slowly move the  linkage. they should eventually free up

Can the carbs be rebuilt once they are loosened?

Unhook the linkage and try to move each throttle individually. Spray the crap out of them with your favorite goop. 

 

I would say 95% chance they can be rebuilt. Mikuni or Weber? If Weber you can use Hypojets after the rebuild. Much more accurate adjustment.

What goop do you recommend? They are stock Webers

They are soaking in PB Blaster now. We'll check on them in the morning.
