That reminds me to re-check the 220D this weekend, I forgot to wire the throttle wide open while checking, bet it's WAY off! (I got 20 BTDC -- should start there and it doesn't).

Anyway, the 15 ATDC timing for the 60x engines is for the hall effect pickup/pump lock tool method. There is a "pointer" on the back of the IP cam that can act as the trigger for the hall effect pickup OR can be used to lock the IP physically. It just happens to pass the "operating point" at 15 degrees ATDC. If you use a drip tube (and the bubble method mentioned above is nothing but the drip tube method using air instead of the primer pump), timing is 24-26 BTDC.
