Ignition Timing Problem
Hi all,
I just purchased an R32 GTR (no modifications) and am having a few small issues that I am trying to sort out. One of the issues is that when I shone a timing light (set to 0 degrees) onto the crank pulley with the engine warm, at 950rpm, and AC off, it showed a timing more advanced than 30 BTDC. I had to turn the CAS all the way clockwise in order to get the timing to be at 20 BTDC. However, every few rotations, it would jump to a value that's not 20 BTDC. I just want to know if the ignition timing is supposed to be consistently at the same value or if it is normal for it to jump to another value once every few rotations.
Also, after turning the CAS all the way clockwise, I am getting almost no power in low revs when the car is cold (engine does not stall if I clutch in and let off gas) so I am only able to drive extremely slowly until the car is warm. The bypass valve sound is more pronounced after the CAS adjustment. There is also more afterfires after CAS adjustment.
Thanks for your time !
David
