Rough idle, now hard to start

Doc,.

I have a '71 240Z that I bought recently. It was running fine - would start right up and idle nicely. After driving it for 45 minutes last weekend, at the end of the trip, it stalled at a red light. It started back up but would not idle. I had to rev the engine or it would die. Now it is reluctant to start, and will not idle at low RPM. If I don't give it alot of throttle it cuts out. Then when I try to restart it, it wont start..

This car has not been driven much in the last 3 or 4 years. Does anyone have any ideas? I recently changed the spark plugs, and am using the stock SU carbs..

Thanks,
.

Don.

Doc here...I think that it is about time to replace the ignition points and condenser in your distributor. Please replace the spark plugs too with NGK or ND brand ones. With this done, you should be able to have the old girl running again. My advice would be to adjust the valves too, since the intake valves get tight after a period of time, which is about 10-12,000 miles maintenance interval.........I hope that this helps you............

Any info will help." Read Doc's answer to Frosty and other Datsun enthusiasts who have sought his advise for the last couple decades on Doc's Tech pages.

280Z Dies SudenlyTravis here(Zonc #98029), in Fresno. I have a problem with my 1977 280z which I can not figure out. It started today. Just driving down the road the car shut off, I disengaged the clutch and it started right back up. I drove it home only about a mile. Tonight I drove it to FSU and it shut off 3 times on the way there, while it was cold and running at temp. I just hooked up a test light to the fuel pump and drove the car. The light is inline with the pump so when the pump is getting power the light is on.
