I would say your carbs are freezing up because of the cold temperatures your having there. You should have 2 Air inlets, one from the front of the car that takes in fresh air and one that takes in heated air off the exhaust manifold. If you put tape over the fresh air inlet and it stops this behavior then you need to replace the diverter between the 2 because its not working. I dont have a Z car and cant be sure that they work this way but I have seen this happen to several other older cars, especially if they have had an aftermarket carb installed. Hope this helps

Thanks John, I already have checked most of those things the only think that is beyond repair is the battery box. Its completely rusted through. The rest of it is very solid. I didnt check the floor pan from inside but I can replace those easily if they turn out to be bad. They look ok from outside. This car is from texas so I didnt expect to find alot of rust but it was better than I hoped. I plan on a complete frame off restoration. I will be doing everything myself except the paint, I have a good local shop I will take it to for that.

Hi all, I have a chance to buy a one owner 1970 240z for $600. It has some minor rearend damage and the front wheel bearings are frozen. It has a small amount or rust but is in generaly sound condition. I have priced the parts I think it will need and added some extra and I figure it will cost $11000 to restore. I guess my question is would this be worth the time and expense?
