So I had a slipping clutch which was due to gas leaking into the works. Used brake cleaner to fix that. But, after removing the side cover, things look really ugly in there.The big gear has side to side and up and down play and lots of it. When the big gear is pushed far left, it barely engages with the engine gear. Compare the first and second picture and you'll see what I mean. In the first picture, the gear is pushed down. In the second picture, it's pushed up. Also, the cover was full of black dust, presumably clutch pad material. See the third picture which is the pile of dust emptied onto the garage floor. Is this repairable at reasonable cost or it's time to move on to another engine? Are all HT's more or less at this (low) quality or is there a better supplier?
