To help reduce confusion, lets standardize terms.. The burn tube is the stem that is between the PC and the cylinder. The Burn holes are the angled holes at the tip of the burn tube.
Do I understand you correctly that you drilled out the inside diameter of the burn tube (you would have had to remove the impingement ball) the first time, and then tapered the inside diameter of the burn tube so the PC end was larger in diameter than the inside diameter at the tip?
Or are you saying you drilled out the smaller burn holes at the tip? Then tapered the burn holes?
For example, I removed the impingement ball and tapered the inside diameter of the burn tube, then eliminated the three burn holes lol... I did not touch the two small rear burn holes.
