Wecome to the Forum! It is nice to see another "blaze" 74 B on the road again. The best advice I can offer, when looking for problems, is to not bother...they will find you soon enough
Seriously, the best thing you can do is sit down for a couple of hours (or days even) and read though the old old posts and follow some links. That will give a you good idea of problems and solutions that others have had.
The LBC Forum is a great resource to have and lots of good information, if you just read though alot of the BS (entertaining too sometimes)and follow the links to other sources and so on.
Good Luck with your new hand me down toy!
