172- Rattle/Shudder fro Manifold

[Darren16v]

My Phase 1 172 makes a rattle/shudder from the manifold about 1500-2500 revs. Worst when cold- not so noticeable when warmer. Anybody had similar problems? I have had a look and can't see anything obvious loose or cracked.

You'd need to find where it comming from top or bottom of engine. Might be a few things.
