New Motor problems...

[tnm27]

Hey guys, i got done swapping out my old motor with a JDM Cyclone motor, but I ran into a couple problems, and I'm stuck as to what to do. The motor starts, but it's a really crappy start up, it jumps to 4k at the start than drops to 1k rpm, after that it idles really crappy for about 5-10 seconds than dies. While it's doing that, there is a loud whistle from around the intake manifold, I checked for air leaks, but can't seem to find any from around that area....or else I'm not just checking hard enough...I used a timing gun to check the timing and it's a little odd....Everything will be good, but after a couple cylcle's the timing marks start to jump like crazy. I fixed the CAS to the point where it doesn't jump too much but the timing is better than before. Should I redo my timing? what are any suggestions as to what the loud whistle is? Anything would help, Thanks.
