Sorted out my various issues.
Ok it was not fun when I got started.
But after spending some time with other smokers I was able to sort out all my issues.
a. The first mistake I was making was to try using what Im told are magic coals. Or coals that are designed to light easier. These have a chemical covering that speeds burn but it also prevents the heat from transfering from inside to the foil and tabaco. So just use regular coals or use the square type.
b. Problem of only the top layer was geting burnt leaving a lot of un burnt tabaco underneeth.
The reson for this was the crappy pre-cut foils I was using. Switched to using regular kitchen foil and folding it twice over. Now my complete bowl burns thru even and there is no burnt or roughf smoke.
