[QUOTE="Rhodester, post: 785902, member: 42241"] farmerj, the 200H engine only has 7.9:1 compression so that gives a pretty good safety factor from the bad effects of advancing the timing A LITTLE too much. I have mine at a little more advanced than the most advanced mark (about 1/2 of a space past). I like the results of a snappier and cleaner running bottom end. Eric Gorr suggested I could go a little beyond this even. In addition I had my cyl. base shaved a little to increase compression (only enough to raise it 8 lbs. on the compression tester). I think it's now at 142 lbs. I still never overheat or detonate and my top end seems to rev as far as it did before. I run 91 octane pump gas and MX2T at 40:1. All in all I got the effects I was shooting for with no negative compromises. [/QUOTE]
