I have a 2 part question. I am replacing my freewheel on my 1985 Fuji League. The current one is a 6 speed Suntour Mighty, standard spaced. I believe the new one is the same, (I am getting it from someone else). Anyway, if it is a tighter spacing, do I need to add washers somewhere to keep the chain alignment proper?
Also, recently, after a sand blasted ride, I cleaned out my cogs, derailleur and chain; however, recently, I've been getting a strange somewhat grinding sound from the backside with my chain (freewheel or derailleur). Anyway, it occurs more often on hard cycling and happens between too many turns to be a particular link in the chain. Is there some common problem this could be?
Is there a good chance after replacing the freewheel and the chain, I will be free of this problem?
Sorry to be not direct or specific, but it is confusing me with my minor knowledge.
