if it is tight, i would contact the retailer where purchased, i have seen maybe 4 pins tight from nova based engines in the last year. one of them badly wore the piston in about 1.5 lts of fuel. if retailer wont do anything, i would try a new wrist pin. if that one is tight, i have some very fine bits for light polishing work. i would polish the piston very carefully and only to make it feel looser that the piston will rock in your hand if tilting the rod from side to side.
but first contact the seller before anything is done. give them the choice to replace parts, or the engine.
