Just came in from the garage trouble shooting the TR3's rough running engine.
The engine is missing at low RPM (900 to 1500)consistently High RPM (3500+)intermittently
Cold high RPM smooth
Warm high RPM rough <span style="text-decoration: underline">sometimes</span>
Acceleration is always smooth
The step by step actions are listed below. I'm making a change one at a time to ID the problem. I'm stuck on the ignition system and will try the carbs next.
1. Replaced wires- no fix
2. Replaced MGB cap with correct cap - no fix
3. replaced Rotor - no fix
Next steps:
1. Replace points
2. Replace coil
3. Move to carbs.
QUESTION
The plate that the points are mounted to wiggles. It moves up and down making the little red plastic cam follower face change from being parallel to the cam to being at an angle.

Is this correct? Seems that should be a constant "flat" against the cam.
How can this movement be taken out of the points if it not to be there?
Any suggestions on where to go next?
