My built mini bike won’t rev past about 3600 rpms

I built a predator 212 cc mini bike and I tried cutting the the key to advance the timing because I put a .308 cam in it and it needed like 34 or like 36 degrees of timing advance and I have a Amazon built flywheel that did like 26 degrees of advance timing and it still won’t rev past roughly 3600 rpm could this be a like leaking valve or retarded timing and I know it’s not the coil cus I put a msd coil in it and I just don’t know what to do just looking for options. Parts in it
Built rod and fly wheel

X rockers
36lbs spring
308 cam
