doing 70's vintage 4 cylinder inline honda bikes, it came with a JC Whitney carb
balancing kit. I never used it, as colored water was easier to handle and less f
a spill issue. I think it is about a full pound.


As for the odors, some of the classic oils are my weakness, especially whale
oil. I'm not old enough to have bough any, but I have worked ion some equipment
over the years that was lubricated with it, and have used some NOS from sealed
bottles.
I am curious why a winery would have picric acid, though.
