I have 87mm pistons, a Kastner G3 cam and about a 12:1 compression ratio. I am using about 19 degrees advance at idle (no centrifugal advance) and 30 degrees advance at 3000 RPM. I don’t know what I have at higher RPM’s because I never looked. I’m currently doing an engine rebuild so I will have to look what I’ve got at the higher RPM’s when I get the engine running. I’m curious as to what others are using and if anyone has done any testing on a dyno with different advance curves.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks in advance for your input.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Tim Murphy<o:p></o:p></p><p class=MsoNormal>#317 BRG TR4<o:p></o:p></p></div></body></html>
