Did you do a compression check after re-assembly?
I soft seized my old Metra kit like 3 times when it was new, and after I got it jetted right and mixed the proper amount of oil to gas, I had no more issues for about 1500 miles.
As long as there are no major scores/scratches in the cylinder and the piston/rings look ok, I would think the kit would be fine...
However, I have zero experience with the hobbit polini kit...
Good luck.
