TDC Down and dirty: Stick a screwdriver in the #1 hole and gently find a place where it will pry in there cocked in hole and cylinder wall. Turn fan until crank turns piston up into screwdriver (youll feel it). Mark damper at 0 now turn crank in opposite direction until it hits again, mark again at 0 (2 marks now). remove screwdriver and straddle tab 0 with your marks, there is the real TDC.
