Pork picinic.  1.5 to 2 ounces Morton tenderquick dissolved in 10 to 12 ounces of water on a 8 to 10 pound picnic.

Inject with meat injection needle and let sit overnite in fridge.  More or less tenderquick will change the hamminess flavor. Don't need it, but a small amount of sugar gets it pinker. Thats why the sugar in hams. 

Put it in a tinfoil roaster pan and smoke at 180 for 3 -4 hours then crank up the heat and let er cook till the bone sticks out the meat real good. If you get it cooked enough it pulls apart.
