Re: advanced timing ?

i highly recommend this method, very simple, but you use 4 degrees less so you are looking for 15 BTC, then you have to set you throttle linkage to match the timing. it is called synchronization. there is the exact procedure in the OEM Service Manual. http://forums.iboats.com/showthread.php?t=228183
