Hey guys I am new to grilling and I love it! I am using a cheap $20 walmart grill but it seems to me that everytime I grill there is a 50/50 chance that the coals will not be hot enough to cook at all. Maybe it is the charcoal I am using cause I buy the cheapest stuff I can find douse it in lighter fluid and light it up. Should I be using a chimney? Any help would be greatly appreciated..
