My best guess at the moment is that the new starter dogs ( two high torque motors tried ) do not line up with the ring teeth - fitting he original motor - if it works will I think clear out all the other possibilities. There is a solenoid in the circuit - fitted to the motors not a remote one.

Fitted a original starter today - just the same. I have now put the first high torque motor back on and it just spins away - powered by a remote battery with new lead - solenoid powered by the same remote battery. So the motor is not making contact with the ring teeth - the teeth look ok when viewed - no damage. Tomorrow I will try the new high torque motor back on just to be 100% sure its not the motor. plugs removed and engine turns ok by hand. Sick as a chip as they say locally. I don't have any room in my garage so the next step would be to take it to our nearest garage - it should bump start - gearbox out to see what is going on with the flywheel ring - not going to be cheap but I do have a spare engine I can take the flywheel off if all is duff.

I can only sympathise Peter, I also seem to always have problems that no-one can understand (not even my psychologist)

OK today's effort. Fitted the motor to my spare engine and it works but it is very tight and the teeth do stick together for a while when the motor stops ( sometimes ) so rather than taking the engine out and changing the flywheel ( take the one off my spare engine - later type engine ) I think I will clean the ring teeth up with a file first - after all it is 51 years old and the motor banging away at it for that long is bound to have "flattened" the ring teeth somewhat and I have nothing to lose by trying that first. Maybe filing a bit of play in the motor body will allow me to move the teeth away from the ring by 1/2mm but that is a 2nd option. Changing the flywheel is the last option and a job for May or June as I a) cannot start the car to get it where I want it and b) have to work outside anyway.

Tried taking a bit off the outside of the starter motor to get it a bit more play when fitting - engine turned but very noisy - now given up and ordered a new ring gear - engine coming out May or June depending on the weather - as it will have to be done outside in the street.

I cannot remember - will the engine come out of the Coupe without removing the manifolds ?

Cast or tubular manifolds?

cast currently fitted but I do have a pair of tubes hanging in the garage - off a 5 so they will probably need modifying

The drop between the coupe and SE5 are different I believe as the exhaust runs through the chassis on a coupe .
However I have never tried

They can be cut and shortened or lengthened - not a big problem and I got them for nothing so spending a bit is not costly. Ordered a new flywheel starter ring ready for the good weather - could be a while. First I have to make a bit of space in the garage for the hoist and engine.

Just wondering - IF the starter pinion gear diameter is "oversize" and interferes with the starter ring, are you sure that a new starter ring will improve matters?
Do you have a "good" and a "bad" starter to compare pinion diameters?

New cable down to the starter and a cable directly from the battery -ve to the engine.
just gone back through and noticed this - is the earth cable new and/or have you bypassed it with a jump lead? I had an intermittent starting problem on a Fiat strada which turned out to be the Engine earth cable corroded and separated inside its plastic insulation.

The battery is connected directly to the engine with a independent lead as is the chassis. I have tried a separate battery connected to the engine and directly to the motor - I have also tried the starter on a spare engine that I have and it works fine - it all points to the flywheel ring even though it looks ok through the starter hole and at the bottom with the plate removed. I have also tried three starter motors - the original Lucas type and two high torque motors one of which has been on the car for a number of years and worked ok and the other is the same type but brand new
