we have this business in ri/ct that is called electric boat. they make submarines. i have some buddies that work there and they get me what we new englanders call e-b green. its baisically duct tape but better. that is what i carry. i also like to carry an extra pull chord. just in case one of mine breaks on my 2 stroke stuff or my push mower. oh and i carry sand paper so if you dont get a spark out of you spark plugs you can try to sand some of the oil and junk off of it and you might get a spark. you know what i mean?
