Ignition timing.


New Member
Mechanic was doing a bit of work for me so I asked him to set the ignition timing.
He said there is a TDC mark and 4 other marks. What are the other marks? And also is it 20 degree BTDC with TPS plug removed??? And is that at idle???
Look at right hand side of plenum, just below the inlet.
and its below that and slightly forward. Usually has a green colour bracket about it.
