Does anyone know what the timing should be set on a CA20?dual spark ones. dont know shit about these motors. Its in a 84 gazelle. Thanks

Did you find the info? I need to do the same on my Gazelle shitter :D
Any chance you could tell me which way your coils are hooked up? The leads going from the coild to the dissy caps fell off so I am not sure if I have them hooked up right.

3-5 degrees @ idle....but thats for an 86-88...is that the same as yours..my info doesn't go back to 84.

have you got any idea if it is timed off the inlet or exahust spark plugs?

Ignition Coils: Mounted on the passengers side front apron.
Both ignition coils operate the spark for one high tension system.
Note should be made of the orientation of the inlet and exhaust high tension leads on the distributor cap.
1. Engine to operating temperature.
2. No engine load.
3. Gear selector in Park (A/T), Neutral (M/T).
4. Disconnect and plug vacuum lines to distributor.
5. Timing should be:
0 ± 1° BTDC.
6. If not to specifications, rotate distributor.
That is different to the spec I gave before...so I did a bit of digging and found the ****up...its meant to have an airgap of 0.3-0.5 mm between the rotor and reluctor.
It appears to me that the both systems should fire at the same time so therefore either plug should do....but don't make me dig out my trade books on this one...we had to study this design but that was 7 yrs ago.

Thanks heaps!! I swapped over the inlet and exhaust coil leads and it made a big difference, so at least I know I have them the right way now, before it was very flat up until 3,000rpm.
