When I rebuilt the motor in my TR3A I reused the old distributer. Put new points, condenser, cap and wires. Timed it up and it fired on the first try. Great.
I had noticed the distributer had some play in the main shaft so I got a new distributer from one of the big 3. The old distributer is a DM2 with side exit plug wires. The new one is a 25D with top exit plug wires.
I put the new distributer in the car but left the cap in place as I did not have the push in wires the new cap takes. No start. Check the timing still no start. If I pull the coil wire off the cap and flick the points I get a great spark but putting a plug on a wire touching the head I get no spark.
Checked all the dimensions I can think of in the caps and the height of the rotors and they are all the same.
I am not sure if I have swapped the rotors when I swapped the distributors.
Putting the old distributer back it starts right up.
Any thoughts.
