Please help me
I have a 1969 for 2 years now and I went to the city 2 weeks ago and it was parked. On my return the car started and only ran for 2/3 seconds. I then continued and I was lucky to be at a meet and a mate got me running by flooring the accelerator each time the car ran for longer before stopping again. It ran like fuel starving. On the day it got going and ran perfect. Ever since the same problem. The car has been perfect up until then. I have tried the following.
Replace fuel pump
Checked fuel supply
Checked points, condenser, ciol, plugleads
I can get the car going as it did on the day trouble began, during this the car coughs and backfires but will start after a long while.
Please let me know what I can do next.
 
Replace the condenser, and check the float bowls in the carbs, the float may be sticking or there may be a build up of crud inside.
 
Hi, An AED is Automatic Enrichment Device It was fitted to early V8's, it's temperature controlled and raises the level of the fuel in the carbs thus enriching. They can be quite troublesome and can flood the engine. It's located on the manifold in front of the left hand carb.

AED is in fact a third carburettor which supplies a rich mixture to supplement the other two. Notoriously unreliable but now available again on exchange from Burlen Fuel Systems
 
had. starting issues then running. with my v8. despite new plugs.leads. condenser ,points .rotor arm .cap and timing check. then looked at carbs ( HIF) used exchange refurb kit to stripped and rebuilt both. always got poor starting and when decelerating engine can cut out and refuse to restart for a few minutes. with carbs done as well as electrics I put those metal ' tablets' in fuel tank . added a fresh. gallon of super high octane and hey presto. it now starts on choke fairly easy. still cuts out but not at lights etc.. only after a stop eg. meeting others in a lay by.. where I think its fuel gassing caused by heat .. so with just that one issue remain have been advised to dump mechanical fuel pump and use electric.
 
Replace the condenser, and check the float bowls in the carbs, the float may be sticking or there may be a build up of crud inside.
Dis that no good, by accident i moved the wore onthe brake switchand the car started first turn. I don'tunderstand why.
Any comments?
 
I can now start with no problem. I cleaned the spades on the brake switch and all ok. I do not understand why. Do you have any idea?
 
If you mean the switch on the reservoir for low fluid warning, the earth for the starter relay is piggy-backed on to the reservoir switch, so bad connections or wires adrift there stop the starter relay working.
 
It is the switch located on the brake fluid block front left near the lights. The car is still failing and when i wiggle the wires the car will start. I have put new spades on.
