this is where the marks are the one on the LEFT is the L 5 ATDC the one on the RIGHT is the T 20 ATDC, you can see where the are in relation to the keyway. this is from the engien side so its BACKWARDS.

kahren

this is the pulley boss and you can see that the dimple is NOT where the TDC is

Cheers kahren!



Very useful those pics were..



I've found it now, now one last question if I may..



When you say you have to hold the CAS straight while putting it in, I tried that but it REALLY still wants to turn.. How do you usually stab it in?

kahren

it will usualyl want to turn a tad, thats why i open the cover and hold those 2 blade lookign things with my fingers to make sure ot doesnt slip a tooth off or so.

Wow, great, did all this got it started but its running shiiiit.



_WAY_ too much fuel, I didn't alter any of the maps on the microtech so it MUST have a stuck open injector/shat FPR.... I did hit 18psi(accidently of course) on stock 460cc injector and N/A FPR.. so im not totally suprised if it is shat



Grrr time to pull the manifolds off again.. and upgrade..





Unless anyone else has any bright ideas on what it could be? (actually on second thought i'll start a new thread, don't wanna clutter up this gem )

taking it one step further with a timing light on a running engine ...



do the timing marks move to the intake/exhaust side of the engine as it advances, or is that getting more retarded?

kahren

if the marks on the pulley are moving to the left then the ignition timing is being advanced, the marks moving to the right its being retarded, it shouldn't retard any more then it is on idle, so revving the motor up you should only see the marks go to the left

thanks for the reply ...



yeah, i know it shouldn't retard any more than idle once you start to rev, but i guess in my mind i had it that advance and ATDC were the same, but i guess i have some homework to do on timing ...

kahren

to make it more lear for you, advance means that the ignition timing sparks BEFORE the TDC is reached. the higher you rev the more time you need for the fuel to burn, so the timing needs to advance to keep that time the same or close to ideal. the more load you put on the engine the more it needs to retard, but at the the same rpm with no load (gas pedal resting) and full throttle the timing only needs to be retarded usually anywhere from 5-10 degrees so the diffrence is in timing is not as drastic as the timing diffrence between idle and redline. hope all is clear.
