ok well we noticed this problem when we picked up the car, we took her out again today, me dad seems to think the carb is floddin at part throttle.

the car just boggs down and makes the whole car surge forward, but if you let off a little its fine, or of you push right past it its fine. what do you all think, it happends if i have the turbo running or not. ("turbo" off a 84 300zx, its more of a electric blower)

thanks for any help. im gonna fix this, and then probally try to track down the oil leak i have thats dripping onto the exhaust. and then try to make a new muffler settup taht will make it sound a little more beastly, but not loud.

I had this exact problem with an 87 carbed 4x4 wagon.
This fix was given to me by Kerry at Roobuilders, he is IMHO the man when it comes to Hitachi carbs and their problems.
Here is a link you can ask him directly
For a test only. On the aircleaner housing snorkle you will see a small solenoid. Remove the line from the carb to this solenoid and plug it.
Take a test drive and see if that cures the hesitation at part throttle.
Good luck, hope this helps
