Have gotten old and forgotten a lot.

I have an exhaust leak somewhere. I am going to pour a tad of MMO down the carb and see if I can find leak. If it turns out to be a leak between block and exhaust pipe, i.e. a leaking gasket, how is best way to drop exhaust pipes? Loosen left side bolts/nuts, then cross over pipe on passenger side, and drop it down enough to replace gasket(s)? Or am I missing something? I hope it is that simple. Of course I will tighten everything first and see if that helps. Thanks in advance. Lawson
