Depending on where you are walking there will almost always be a form of tinder that is more reliable than liquid fuel. You can't beat lighter pine, birch bark, cedar bark, or alder twigs - to mention the most common tinder. They break the rules. For instance, alder lights wet or dry, green or cured. Lighter pine is the skeleton left when a pine tree rots. Birch and cecar bark are self-explanitory. Learn to spot these materials and you will never need to carry charcoal lighter again.
Consider making a larger hole for lighting. It should not compromise performance. Touch off a few slivers of lighter pine in the bottom compartment, and there will be no doubt about your fire starting.
However, until you feel comfortable with your woodcraft, consider making long-burning matches by soaking wooden, strike-anywhere kitchen matches in melted parafin. Melt parafin in a double boiler - something like a coffee can in a cook pot of boiling water. Submerge the matches (I just sink a box at a time). Let them soak for 5 minutes, until they are hot enough to let the excess wax drain off. Remove the box and drain it. Too much wax will interfere with proper ignition, so ignore the old advice to fill the match box with parafin and break out matches as you need them. That doesn't work. You want the matches to seem almost normal. These wax-permeated matche sticks will burn a long time and will light a stubborn fire. They will also be reasonably waterproof.
