I recently had the head off of my 606 engine. After reassembly, here are the issues:
1. Difficult to start
2. Once started, engine runs very poorly. will struggle to stay alive when cold, but when begins to warm up, if I don't keep foot slightly on pedal it will just die.
3. When idling, it smokes like crazy.
4. The second I drop it into gear, engine dies. Even if I try to keep a little pressure on accelerator.
