Thank you all for the help... I am getting used to needs to get it running again I have the Briggs covered, but I'm too new at mini bikes to know what I need. It appears that someone put a pretty Janky and home made friction foot operated brake ( see the #2 pic) on this bike and I think it used to have a drum style inside the sprocket. Is a dished out sprocket a sure sign that this is what it ran? anyone have pics? I have no problem converting to Hydraulic disc, in fact I'd kinda like to... Have welder will mod! turns out my office very close to Go Powersports for parts.
