When I do the 139qmb motors, they all do that due to the magnet. When I do the timing of the GY6 125/150 motors, they stay in place. What you are experiencing is normal. Timing doesn't change. It should be at the "T" mark. I don't hold it. I kind of adjust for that difference, then double check after the chain is on the camshaft.

i dont know what you mean by "adjust for the difference". so basically the cam chain will hold it in place? or are you saying that i should turn the cam timing a little clockwise to compinsate for the difference on the flywheel?

Just time to the "T" how ever you can. Whether it stays in place or not, it still has to be timed correctly. Double check your timing as the T doesn't stay in place. "The difference" is your best guess where the camshaft should line up with the T since the T mark isn't exactly in place. This isn't exact science, this is learning via experience. Always double check your camshaft marks after. You can do this by holding the T mark and looking back at the camshaft after it is installed.
The fact that it doesn't settle on the T mark is irrelevant. My guess is before you had the everything installed, including the spark plug. This would create pressure in the cylinder so it doesn't turn as easily.
Just try to time it correctly and see what you learn.

You could take the stator out for the time being and then put it back after your valves are adjusted.

i havent messed around with that area i just take the bolt off the flywheel then what? would be anything extremely important not to do if i did that? i think it would be easier if i just try the compinsate thing. but i would be willing to try it ill look up some videos about how to take that area apart.
