its because its still very tight. the piston is AL and Sleve is chrome plated brass. The two metals have different expansion rates. When the engine is below full operating tempreature the piston sill want to stick in the sleve at TDC (Top Dead Center). After you get it warmed up the tollerance in the piston/sleve opens up a bit more and it runs better. As you break in the engine it will get easier to start.
