I have a feeling mine will be around 160-170...it'll be interesting to see the results.

No one that I know of is in any big hurry so take your time. I think it makes more sense to come up with a good base set of measurements, and then develop a formula for porting the saw than to be in a big hurry to run the saw. I have a trashed 665 jug here and have been looking at it trying to determine in my feeble mind (since finger ports are beyond my experience), if finger porting would add to or diminish the torque the saw already produces or if it would ultimately be unnecessary. IIRC, Randy has done them on 262XP saws but I don't have a good understanding of what advantages they provide and in what situations they might have a positive effect.

Hey Adam, what exhaust height would you be using?

On a 65cc engine I'll be looking for 102 - 103 atdc.
