72 does that. That's the only year that pushes coolant from intake manifold into the carbs.

Good luck and here's to hoping the fix was as easy as a couple new gaskets!

I removed this inline intake manifold and place some brass nuts at the ends of bothe carbs. Does this have any effect on then performance of the car once started? I live on a tropical weather country were no heater is needed.

PS, leave the water system alone, removing it will hurt drivability on warm up and gas millage.

 

I'm sorry but I disagree. If I lived in a colder climate, maybe but my carbs are cool to the touch after a good drive since I plugged those coolant lines. 

Gas mileage in my situation is I must drive the car to keep the fuel from losing octane.  It's my favorite chore I have, driving my Zs to burn the flat gas.  Life is tough at my house.

  tzagi1,

  Thank you for taking the time to type in the gasket making information.  I wondered what type of cardboard might work.

  siteunseen,

   Not knowing a lot about carbs I left the carb water heating hooked up with my only reasoning being that the manufacturer knows more about carbs than I do, though I am willing to do independent thinking too, and to take advice from forum members to possibly remove carb water heating.  I live in a warm Arizona climate.  I should be able to evaluate carb performance in this climate better once I get them reinstalled on the car and have an opportunity to drive the car when it is really hot.  Since I recently relocated, I haven't been here for the hot part of summer yet.   

I ran the factory design for years.  After I rebuilt the motor I read up on what I could delete to simplify the engine bay's looks.

It'll run fine in my opinion with the coolant flowing. I eliminated potential hose failure is all.  Nothing to do with performance. 

Hopefully you'll have it on the road soon. 

That was my thought for water heat removal, get rid of hoses that might fail.  Should get the carbs back from Z therapy around the end of December.  Can't wait for that!
