EARLE Perfect line up on liner in cylinder piston step 180 degrees around from exhaust and yes the lip on liner fits recess in cylinder. The compression still might be too low for a fire off, this piston/liner best of the lot others almost no compression, lots of wear martin
We did use the 70/30 mix not a poptried a few drops in the MPJET 061 2 flips and screamed like a banshee

will have to scout around for a decent piston and liner
