Moped Army

Got a 2001 tomos with the A35 engine on it that needs a bit of work and a 1980 silver bullet with the A3 engine on it that also needs some work. I would just really like some experienced person's advice and guidance to show me how to fix these peds up so I can do it by myself the next time something goes wrong. I learn best by example so having someone tell me what to do on these forums isn't as effective as someone showing me in person. I wouldn't mind setting up a date and meeting somewhere in the future before it gets to cold, maybe a wrench and ride?(emphasis on the wrench)
