the engine will tick over for ever ,then try to rev up it will bang and spit ect.
the car is a basic locost,have replaced points condenser cap and rotor arm many times.

does it run with or without ballast at the moment ?

what type of coil is it ? (12v or 9v)


had this issue a few times on my mk1 fiesta, in the end we reconned that points just arn't made as well as they used to be
have you considered upgrading eletronic ignition ? (once its set you'll never need to adjust it again )

Ive fitted this to my xflow, nice and easy job done, and no more points

Ford crossflow Engines AccuSpark® Electronic Ignition

there a few different types of dizzy on a xflow, so you will need to know which one you have

regards

steve

You either need to fit a ballast resistor or change to a 12v coil


suitable 12v coil Genuine LUCAS High Performance Standard 12v Sports Coil DLB105

Is the resistor or capacitor ( or whatever it is) on the side of the dizzy OK?
It would be best to change to electronic though.

I had the same issue on my Pinto, went through 3 sets of points before I gave up and went for the basic electronic with the amplifier. Works fine now

Burning is usually a sign of condenser problems. Also not having the correct ciol/balast resistor.

Although these aren't usually described as "burning out"; A couple of common mistakes often made when fitting new pionts that cause problems are...
Not putting grease (just a dab) on the cam, causing the follower to wear out.
Not cleaning the points surface (or feeler guages) of any grease/oil before fitting.
Checking the points gap with feeler guages on used/old points. It's best done by measuring dwell angle.

Points burning means wrong coil for the distributor
Accu spark also suffers if you have the wrong coil

As i am waiting for my mate to one day finish this ECU, he built me a small PCB, which basically takes the load off the points when switching, seems to smooth out the idle as well. I am sure you can buy what I would call' points assist' units, if not drop me a line if you want one making up.

It has been done many times, assisted contact breakers systems s bring their own problems they run into problems because breaker points need enough current to burn off any dirt anf oil deposits that get on the contact surfaces.

Yes we know that which is why this one drops the assist now and again to enable the surfaces to be selfcleaned.

Coils and Ballast Resistors 101

Back in the day of points ignition Fords, Vauxhalls some Triumphs and cold climate export models of other makes had ballast resistors to ease starting in cold weather when battery voltage is low.

A ballasted coil is a lower voltage coil, hence the engine is running the voltage across the coil terminals of a ballasted coil in a normal car can be anywhere between 6v and 10v depending on the car manufacturer . Cars with Delco ignitions system had the ballast resistor bolted directly coil terminal while the Autolite/Fomoco ignitions systems in Fords from the 1960s up to the Sierra and MK3 Escort used a resistor built into the wiring loom.


During starting the 12v feed to a ballasted coil coil is arranged so the ballast is by pass this is normally supplied by a special extra terminal on the starter solenoid

The important thing is not use a coil designed for use with a ballast resistors without a ballast or it will burn out the points in a couple of days use.

If you don't have a ballast resistor fitted just use an normal plain 12v coil (for example one listed for a 1970s BL Min or Hillman Imp). You can use any 12v coil with any points distributer the only real difference between a a normal 12v coil and a ballasted type is the internal resistance of the coil.

The other important thing is only use a coil designed for points ignition don't be tempted to use one off a car with electronic ignition.

If you have a ballasted coil and ballast but don't have a starter or solenoid with the extra terminal you can wire a relay to supply 12v directly to the coil + connector when the starter is working.

With Ford/Autolite/Fomoco distributer clean and plastic flash of the cam follower heal of the points before fitting and set the gap and always lubricate the cam with a tiny amount of grease. Also with new points to the wide end of the range specified (ie Manual specifies 0.023 to 0.027" so set to a fairly loose 0.027" then run the engine for ten minutes and re-check the gap you will usually find it has closed up.

deffo wrong coil by the sounds of it.
you need to fit, as others have said, either a ballast resistor or a non ballast coil.
Or for for preference an electronic coil and amplifier (with its matching coil) luckily the electronic distributor from the Mk2 fiesta's has the amplifier built into the distributor and it is a direct fit onto the cross flow's engine (one of my kits has a 1300 cross flow in it and this is what i have done.)

^^ self centring and carb tuning have both been covered before - have a search through the old threads

if you don't find what your after you'd be better starting a new thread for these issues
