BSA MK2 disassembly

Anyone have instructions on disassembling the fire control group on a BSA international MK2? Looking online I can't find much detail.

I have some old oil and gunk in the action I need to clean out. I plan on putting the parts in an ultrasonic cleaner with ballistol. I was also debating putting the whole assembly in the cleaner, then spraying with WD-40 and compressed air to get any water out

Easy to clean it by simply spraying it with either carburater or brake cleaner.

Then blow dry.

Do not use WD-40 on a gun, unless it is just on the outside to protect the finish.

Only time I use wd-40 on guns (or motorcycles) is for getting rid of water. I learned a while ago the the WD stands for "water dispersal". I like to spray things down with it when they come out of a water bath or ultrasonic cleaner to get the water out of the tough to get to spots, then wipe it down and coat with CLP
