That's a Stupid Question!

Wrong!  The only stupid question is one not asked... if you have a question about something, instead of doing nothing about it, thinking it will either get worse at which time you will then worry about it, or it will go away and you won't have to worry about it.  The sooner I  know of something not quite right, the better chance I will have of correcting/repairing the problem before it becomes a bench job.
