I have a bernzo torch tip that clogged so I poked one single whole in the tip very small. Now instead of a regular torch flame it has a standard lighter flame why and how do I get my Torch flame back

likely some solder got into the tip and hardened. look inside to see if this is the case. you will need another torch. hold old tip with tool or clamp. heat hardened solder until it runs out of the old tip. (while still hot), blast it with compressed air after it runs out to clear the rest of it.

Why do you need to burn it for that long? If it is a small 'blow torch' style lighter they are only designed to be lit long enough to light a cigarette or cigar. If you need a flame source for longer periods of time you're better off using a full size blow torch.
The smaller cigarette 'torches' are small and made of lightweight parts. These can heat up the whole lighter. Possibly causing it to the burn the hand or even exploding!

Too much gas! Turn it down and check that nothing is blocking the airways.

Natural gas, they tell us, is clean burning. Well, it makes good ad copy, but it's not 100 percent true. There are trace impurities in gas, and when they burn they become ash. And over a long long period of time this ash can build up and clog tiny gas orifices, like pilot orifices. The symptoms may be that the pilot will not stay lit, or blows out too easily.

There is also a little "cup" around the pilot light in a surface burner to regulate air for proper combustion of the pilot flame. These can get covered with ash or clogged up with spillage from the burner (see below.) Make sure you clean the pilot area thoroughly.

You can usually clean them out with an old toothbrush and some compressed air, but pilot orifices are generally so inexpensive that it's cheaper and safer to replace them. If you choose to clean them out, use a soft-bristle brush like a toothbrush, and not a wire brush. A wire brush might damage the orifice. Be careful not to push the ash into the orifice and impact it.
The surface burner jets are a different animal. The problem is, that pot that boils over can leave some pretty crusty stuff on the burners. The challenge is to get that crusty stuff off without enlarging the gas holes. Sometimes the crusty stuff is not crusty but gummy, and this can be even more fun to get off the burner.

There's no magic way to do this. Depending on what's clogging the gas holes, you may be able burn it off, or at least char it so it can be scraped or knocked off. Use a propane torch or one of the other stove burners if you can get it into the correct position.

You may also be able to use alcohol or some other non-petroleum solvent to knock it loose. If you do, make sure the solvent is completely gone before you put the burner back into service. (Petroleum-based solvents might leave a residue)

Try poking it out with a straight pin if possible. You can use a welding tip cleaner, or a small twist drill, to poke into the holes but only if it fits in the hole with plenty of clearance. Do not use a drill motor with a twist drill; just push it in and out by hand. Use it as if it was a file. Use a twist drill or tip cleaner that is MUCH smaller than the diameter of the hole. Do not use anything with a remote chance of enlarging the hole. Remember, the objective is to take off the crusty stuff without taking off any of the metal. Sometimes a gas stove burner is just too badly clogged, or the holes are too small, and the burner must be replaced.

Get rid of the flash backs, you are working with low pressure and the will give you problems. Plus with what you are doing they are not needed

Hi:
Probably you are doing everything right but are you sure you are using the right tip for acetylene? Because it sounds like you have a defective tip or a clogged one.

with the solder tip attached push upward on the little black knob on the tip, its spring loaded and on one side reveals a small little chamber where you can see a small flame once you turn the gas on and apply a spark/match to the little opening. keep the knob still pushed up all this time. let the fire inside keep going, if you let the knob down and the window to the chamber closes before it gets hot enough the iron wont work but if you wait for a bit with the fire inside, then right below the tip you'll start to see that area glow red, once its glowing red your good to go, you can close the chamber and the catalyst will "burn" the gas in the area and make heat instead of the fire heating the tip. once you close the chamber you're holding open with your thunmb then the fire goes out, if its hot enough you're set to go, otherwise rinse repeat.

Hello,
Your right side burners probably have small vertical lighting holes that are clogged where the pilot lights the burner. Use a sewing needle to poke each hole clean. While you're at it, poke clean the horizontal burner holes just to make sure they are not clogged either. Are there also little tunnels from the burners to each pilot flame? Make sure those are clean inside and attached properly on each end. The pilot flame should be approx 3/8" tall. Compare the working pilot flame to the non-working pilot flames and adjust as necessary. Each pilot has a small aluminum tubing running to it, the adjustment screw will be on this tube. You'll just need a small flat head screw driver to turn it counter-clockwise to increase flame. Hope this helps. Let us know if we can be of further assistance. Douglas

sounds like your needle valves are worn or damaged,also change allthe q rings in same valves

Assuming the burner's clean, try this solution that worked for me:
Often with a big bottle, people turn the gas off and on at the big bottle and leave the grill valve open. That makes the regulator see a low pressure on its output, which is a potential leak indication. It goes into "bypass". Try turning off the tank, turning off the grill valve, and turning on the tank, then waiting 20-ish seconds before turning the grill valve on.
If the burner's dirty, I take mine out of the grill and run it through my oven's self-cleaning cycle.
