Hi Rob.UK, glad the engine is now in good shape. Yes, you should start a thread in the Victa mower frames forum, since this one is for engine problems. A picture or two of the drive control and the drive mechanism would be useful to set the scene when that new thread becomes an archive. Joe is the man once again for the self-propulsion system, and I'm sure he'll respond. As usual, help from anyone who has experience with self-propelled Victas will be appreciated.
