primary fine Engine runs strong. Terrible noise at low speeds or decellorating (sp). Sounds like something is loose. Does not do when engine is pulling, at high speed or in neutral ??????????? | ||

Check the front isolator and it's associated bracket. It sometimes cracks. That is the aluminum piece that bolts to the front of the cylinder. Also, make sure the nuts which hold on your exhaust pipe are still there. They rattle loose, particularly if the isolator bracket is cracked. |
