I am tidying up my 1978 Honda Hobbit, and was wondering if the pedal chain tensioner nylon gear pulleys were supposed to float 3 or 4 mm from side to side, or if they are supposed to be kept in line with a washer. As it stands now, they are just sandwiched between the retainer plates. I suspect they are supposed to float, but would like more information from those who know more than I do. BTW, the chain was in awful shape- dirty, rusty, and with numerous stiff links. Someone had bypassed the tensioner for some reason-maybe just to get the bike started, and the cain would fall off with alarming regularity.
Thanks in advance,
