Sorry to bring up another locked dizzy thread. but can someone tell me what an optimal angle is for the pickups to be set at?



also can i still run vac advance with the dizzy locked in mech advance(i don't think i can, doesn't make sense to me)

"one tooth off" ? is this true with a locked distributor? if so when i'm installing the dizzy, which direction do i rotate the distributor drive shaft (looking in the same view as pic above) clockwise or counter cw?

 

10-15 degrees
yes the vac advance will still work, becuase vac advance works by moving the base plates relative to the shaft

the mech advance works by advancing the top section of the shaft, relative to the pickup plates

dropping the dizzy in one tooth out effectively sits it about 30 more advanced
EG,, base timing will now be 25 BTDC instead of 5 ATDC with dizzy base set in same position
you do this when locking a dizzy as around 25 BTDC is optimum timing at full load and revs

ie
turning anti clockwise,,the rotor vane in the dizzy has already past the leading magnetic pickup
( the one facing the radiator )
and the rotor button has just finished phasing with L1 on the cap


alternately you can rotate the engine clockwise till you see the first timing mark
then rotated anti clockwise the distance about equiv to twice that seen for the gap between the factory marks ( 30mm on the circumference )
then drop the dizzy in with the normal dot lined up with dash method

 

i was just out dropping the dizzy in. now when you say 30mm, did you mean rotate the engine anti clockwise 60mm? (2x30mm).

 

rotate engine anti clockwise 30 mm and mark as 25 BTDC
gap between leading and trailing marks should be 15 mm
