1. Do you have a DUAL vacuum distributor? Regardless of what engine is
in there, it's the distributor type that determines what timing to use.
Someone may have replaced the distributor with a wrong model at some
point, you can never know unless you owned the car from new.

2. did you adjust the timing precisely as instructed¨
