I see alot of people talking about lump coal. I have used kingsford all my life and never really had a problem with it. Here are my questions. 1. What is the differance, I know lump burns hotter and faster and has less ash. Is there anything else? 2. Where can I buy lump coal? Here is what Im smoking with, no mods... yet. Im still learning what to do. My first task is to get my coal out of the ash that is suffocating the fire. Im still trying to figure out how to do that. I also will be making a baffle at work this week. I also have a question about my stack, it already is at my grate level so do I need to do anything with it?
