So I got another piston to install. When out of the engine it fit into the cylinder easilly and moved easy. But when installed in the engine it is hard to kick start. Is this normal? I don't want to mess up another piston or to vs and have to wait for new ones. So I am not going to try to start it until I know that this is normal or not.

It could be possible the ring(s) isn't aligned on the locator pin on the piston properly. With the plug out you should not have resistance turning it by hand. I would pull the cylinder and double check. You must align the ring and compress it when sliding the cylinder on.

A handy little tip I figured out working with these 2 stroke engines, is to take the cylinder, lay it down with the top(head) end down, and the skirt side up, work one ring at a time, align it then compress it and slide it down into the skirt of the cylinder, then do the same with the bottom ring. Only put it in a few mm's past the second ring. Then slide the cylinder on the bolts and slide the pin through the piston connecting it to the crank.
I also always put in 1 circlip in the piston before sliding it into the piston skirt. Also be sure to lubricate the metals before install.

Nice tip CrazyGuy! I've also found it helpful to mark the locator pins with a red sharpie so I'm not second-guessing whether or not I have the rings lined up when installing the piston. It can be tricky to even see the locator pins in less than ideal install conditions and low light...
It's difficult to know what "hard to kickstart" means over the net- but like Ryan_ott says, with the spark plug out, there should be very little resistance. You should be able to move the kickstart lever easily by hand.
