Ok, I'll get started in a few days. Jag, I'll do your first choice. I've looked at your post quite a few times, but the diagram shows 9 holes. Jag, how many holes do NEED TO drill? What is the least that I can drill for best overall performance? Do I just transfer the mesurements from the 48cc piston to 66cc?
All at 7/32 bit? (The best placement, and the least amount of holes I can get away with to still gain best overall 360 circulation. Can I first mark intake through intake centered for after pulling jug, then drilling?
.......Sorry? What about Boost Port?
