Doug, I don't know where your pulley came from but I wouldn't worry too muc=
h about it either.  Set your engine to TDC according to procedure provided =
by Lynn Hannover.
Something like this:  Make and attach a timing marker that lines up with th=
e starter ring gear; mark the corresponding tooth on the ring gear, count t=
he number of teeth and divide by 360 to determine teeth per degree; count i=
n correct direction on ring gear number of teeth to represent 25 degrees BT=
DC - mark that tooth with a different color. Set your engine to 25 BTDC the=
n go to your crank angle sensor and align the first pickup sensor with the =
crank pointer ... Tracy's Manual gives a similar set of instructions.
Good Luck ... Jeff

P.S. I can see these emails through my subscription to The List and can rep=
ly but I cannot get into the lancaironline.net website ... is anyone having=
 the same problem ?

1) Double row pulley Question
    by "DOUGLAS LOMHEIM dlomheim@aol.com" <flyrotary@lancaironline.net>

Going thru my EC2 installation manual, and attempting to set the timing and=
 the aftermarket pulley I inherited with my engine (from Tommy James), and =
it has five tick marks.  Thot this had to come from Mazda Trix or Racing Be=
at, but their pulleys only have four degree tick marks!  Has anyone used th=
is pulley, and do know what the degree marks represent?  Thx.    Doug
