I've been reading lots of threads about main timing, but some of them are very old and haven't found any recent ones. I see mention of some type of 20* offset or something of that nature. I have the lastest version installed now and noticed that the main timing table has lots of negatives, but the pilot timing has many positives which I understand that pilot timing + main timing = start of pilot timing BTDC. So it kind of makes since, but I'm still uncertain if there is some sort of 20* offset. Would really like to know that before I start messing with the timing any. Thanks.
