Thanks
Yea I recall the adv compression was way up there.
No way they are that high. With a uncut deck they are .060 in the hole, or there bouts. Combined with a 88cc head they cant be much more than 10:1 if that.
I mean a near zero deck -4cc valve relief stroker engine 493-499 cid is real close to 11:1 with eddy heads 84cc
