I will add to check piston to combustion chamber clearance. In otherwards, make sure the pop up doesn't hit the ground strap on the spark plug.
Use an old plug that is gapped properly, install in plug hole, rotate engine over by hand via the flywheel to ensure the piston will not smack the plug ground strap.
I had this same fear for a Husky 350 rebuild with a pop up and base gasket delete. Didn't hit plug but only had .0165" squish... a bit tight for my liking so I installed a thin Husky base gasket.
I should add that the new cylinder I used was a HWY kit. Cylinder base flange was much thinner than an OEM and a Meteor cylinder flange. It looked as if the HWY jug came already machined down. So much to a point that I had to buy shorter cylinder mounting bolts as the OEM bolts would bottom out in the crankcase riser without tightening down the cylinder!
