could you just check that its advancing to a visual 30 degrees and assume its probably working as intended?
Most timing lights have a degree dial so tape isn't needed
On an older engine you would measure the damper diameter, compute the degrees and put a 30 degree mark x inches from TDC. With the electronic ignition (no vacuum, no fly weights), could you just check that its advancing to a visual 30 degrees and assume its probably working as intended? Thanks for the help
