I recently changed the D16 internals into my B16 casing.

During the change-over i noticed that when the drive couplings are at the same position the rotor arms are a lead position out, if the B16 rotor arm is at plug 1 the D16 is at plug 2.

I know that the dizzy's can be put 180 degrees out by having the drive coupling fitted the wrong way but is there any reason why the rotor arms aren't at the same position?

I have looked at write-ups on this procedure and seen nothing about this difference.

Also, what are the clearances needed for the sensors?

I have then set that when rotating the shaft i can feel the sensors stopping the shaft at the positions due to them being magnetic and not catching physically.

Thanks in advance.

 

Just move your plugwires to correct position (pointing @ cyl #1 on dizzy cap @ TDC) if that's the only problem.The air gap is listed in Helms manual,search helms manual for your year...

 

Any idea about the difference in the rotor arm position as all the plug lead positions are in the same position aren't they?

 

I would love to see clear pictures of both distributors side by side. Also list exactly which distributor part #s you are using (TD-28 etc.).
