[QUOTE="vibrac, post: 87772, member: 60"] After a long time playing with these engines to obtain speed type performance I find myself a little bemused with my latest engine its a 90 bore Comet and my calculations have got me very near 7.3:1 compression ratio which I guess is about right for a light weight touring machine for long term use (with a nod to the fact my kick will get weaker and the speed limits more policed by electronics and I expect drones). Also amongst all my MK2 and 105 degree cams and exotic stuff I have found a set of MK3's My thoughts are I should just set the Lucas mag (which has given good service and is quite fresh) at 4-6 degrees BTDC with bob weights closed and let the devil take the fully advanced position (holding a blob of weld in reserve if the advance proves to great). Anyway that is the summation that I have gleaned from sources (including here) comments please [/QUOTE]
