Who moved my flywheel???? Dead Stop Method...

I've been reading all sorts of threads regarding the dead stop method for finding true TDC.

So I decided to fab up a stop tool with an old sparkplug, an M8 hex, some JB weld and my trusy dremel. I then made myself a protractor and proceeded to check the flywheel.

Well, rotating counter clockwise my mark was at 11 degrees, rotating clockwise my mark was 21 degrees. 11 + 21 = 32/2 = 16 I advanced the mark 5 degrees 8O, re-did the process and sure enough, each direction is 16 degrees....

Now, I need to get a hold of a timing light...


EDIT: My numbers were not correct, original 14 changed to 11, 26 changed to 21... :oops: Also, listed my procedure below.

1) Placed protractor and pointer.
2) Aligned the 0 degree mark with original mark, (right side).
3) Rotated anti-clockwise and read 11 degrees.
4) Rotated clockwise and read 21 degrees.
5) 11 + 21 = 32, 32/2 = 16.
6) Rotate protractor so both directions = 16 degrees.
7) The view from clockwise is, 21 - 5 = 16, therefore my new mark is 5 degrees advanced from the original timing mark.
Rotate protractor 5 degrees advanced, check each direction for 16 degrees.

Hope I did it properly, if not please advise me of my mistake.
 
so.....

c'mon kzoo the actual TDC line on the protractor - where is it compared to the original line?

you can expect the timing to the old line to be spot on so in effect what i'm saying is: "what is it out by right now?"

ya, like taffy says. i don't think you were at tdc with your stop. does it slide? or is it a bolt threaded into the plug body?
 
ok

kzoo has PM'd me to say that the lines go:

TDC, then to the RIGHT - early line at i think 10 BTDC, then his own line is nearly equadistant again to the right so he is probaly 7-8mm further and therefore 7-8 degrees around. mine was some 9mm/9 degrees in the same direction.

THERE IS CLEARLY A PROBLEM HERE AND ALL OWNERS SHOULD CHECK.

i'll continue this on LBrown's thread.
