Automatic choke

[martinlaw]

Can anyone help please.

I have just changed the engine in my GTR and the new one has a auto choke (the old engine had a manual choke).

It obviously needs a cable attaching to the spade terminal on the carb - where does this cable go to?

On the wiring diagram it does show a cable in the loom for the choke, but I cannot find it.

Any advise would be appreciated.

Thanks,
Martin.

Martin,
The connection for the choke is down by the drivers fuel tank with the air con connection. I don't know anyone that runs a choke, I just give two pumps of the throttle pedal, starts, then feather the throttle for a min then off we go.

Graham is spot on, thats exactly where that cable should be, mine is currently dangling there.

I do believe the best place for an electronic choke is in the bin..

I have the electric choke and it starts a lot lot better. kick the pedal after 30 secs & the revs drop to 1,000 rpm and settles when warm to 800 rpm.
Its nice & smooth & doesnt cut out (unlike when I didnt have a cheke fitted). Horses for courses but mines a lot better with one for me.

Mine were going to report me to the noise police, but never heard anything.
When I had a new carb fitted I did say 'what about an electric choke' but he wouldn't fit it and chucked it!!!

Electric choke works fine on mine.

I had no issues with the electric choke. In fact I would recomend it for daily driving. I was convinced to ditch it by the masses and the only change I've noticed is that I swear alot when starting at 5am in the morning, attepting to keep the thing quiet.

Going HP Holley now. Hmmm......

Coward, go for the improved starting of a blower......no not the blonde german lass, a supercharger!

I agree - bin the choke. you don't need it and all it does is over rich the mixture and in my case cause bore wash. You could also to change to HP carb and solve stalling under braking and get an extra 10bhp!

If you can start a car in the cold without a choke and it runs fine then it will be rich when at operating temperature. It is true that the choke limits airflow to the front 2 venturis.

The wire for the choke should go to any 12 volt source that is hot when the ignition is in the start and run position.

Thanks for the advice guys.

I have found the wire (coiled up tightly and tucked away under a chassis brace).

Have not started the engine yet, so will decide whether to use it or not later.

Cheers

I was going to reply to this, but thought I better leave it there

[Graham-P]

. . . . but we all know Dawn knows more about his fuel injection than Simon, she could show him on the 'map' in the ECU where it is (providing it's still there! )

Your right, when he phoned up Dawn and she mentioned something about mapping he reached for the A to Z

Don't forget if the choke is fitted it will be on, and stay on, unless you power it so that it opens after time.
The alternative is to tie it open.
