Hello,
Newbie here that just bought a used mini chopper that I am fixing up. I bought it for $100 off Craigslist and need a little help. The Sprocket on the TAV is worn out and needs replaced. I bought a new 12 tooth sprocket for it this weekend(nice to live 10 minutes from Comet Karts in Indiana) but haven't been able to get the driven pulley off to replace the sprocket. After removing the nut from shaft, does the outer pulley just pull off or does the retaining clip have to be removed to get pulley off. I have tried prying a bit to get pulley off but didn't want to apply too much pressure and break something before finding out the correct removal method. Also the bearing housing for the driven pulley is a little loose on the mounting plate. Is the housing just press fit into the plate? Is there anyway to tighten it up? Can the housing be welded to the plate to keep it in place? Does anyone have any methods for getting rust out of gas tank? Has anyone used any of the home kits the come with the rust remover and a tank sealer? I read about putting vineager in tank to clean out rust and have mine filled now and wondered if any one else has tried this and had any success. Any responses are appreciated and I am sure I will have more questions in the future.

hi, I myself had the same issue with the driven pulley housing working loose. There is a clip on the opposite side of the pulley that has to be removed.
Make sure you remove the bearings,(they are a slight interference fit) and have it welded.
