My A14 have a problem,

when i turn the key to turn off the engine,
he only stops 2 or 3 seconds later.

any ideas????

timing? points gap?

yes i recently have changed the points gap.

could be the points gap????

I believe that engines do this if they are running too hot.

sounds like its running on ,is it pinging?
back off timing a little

Ignition timing,anti-knock sensor(if it has one),faulty ignition switch.

yeah my A15 does this 2.... just keeps spluttering and wont shut down so i just pull the handbreak on and put it in gear and drop the clutch and stall it.... i was told it was detonation cus of engine heat plus a combination of carby tuning and timing... bring on the SR.

Does your carb have a solenoid on it? if so this is the anti-diesel solenoid.

This will stop it running on if it is there and working, it was an upgrade on the later model datsun carbs to allow leaner mix without the run-on.

ah ok... no im running twin SU hitachis.... im soon to be pulling it all out and doing an SR conversion so the EFI will save me from the embarrassment of not being able to shut my car off at servos and the shops

fuel solenoid? anti deisling solenoid or whatever you wanna call it. thats if your running the stock carbie thats my guess, mine did the same thing and ran backwards for about 8 seconds

edit: sorry just read the previous post. think thats your problem.
