Hello
My Elan has developed a strange problem.
I can hear a small tick that could be a short around the area of the distributor / carbs
I can't see any sparks. The car has lumenition optronic , solid ht leads, NGK plugs, all new lucas distributor cap, rotor from Sue
Has anyone any ideas?
The car is also running with a very very slight hesitation.
Thanks
Terry

Is the tick random or aligned with the distributor rpm?
Could be the rotor hitting a cap terminal if the cap is not on right if at distributor rpm
Could be an insulation breakdown if occurring at random frequency - potentially in the rotor inside the cap so you would not see.

No I am using one of the new red type of rotor. I have slightly filed the bottom now so it seats right in. Coil is also lumenition.

I have listened with a cold chisel against the valve and it's not that which is clicking.
It's funny it's completely random, you may get two in quick succession and then none for a while.
It's not an external spark so I think I will drive it a bit to see what happens I suppose.

Hmm, is an induction leak a possibility? A sharp intake of air at the carb o-ring?

In the past one things that was used to get a fatter spark to make extra gap in the king wire.
One trick was to use a button passing the wire through a hole and bending it back, so the spark has to jump across the button to wire passed through another hole.
If this was ever any use or just a myth, I don't know.
But if your engine is running better and you jumping spark in the coil lead it might just be true.

hi Terry,
are you sure it's not a cam follower. They do rotate a little and can click when in the worn position
