The problem with your current deck is that yes, you have lots of 1 mana burn. And yes, taken as a whole you can probably kill an opponent given 5+ turns. The problems are as follows:

1. You're going to run out of steam right around turn 3-4 (if you drop a land per turn) and your opponent won't be dead. This is because you have no card draw or card fixing so you're at the mercy of the draw + you're only going to draw 1 card per turn. This is a major problem with most burn/rush decks.
2. Your burn cards don't deal as much damage as other options. You have lots of 2 damage burn. For the same price you could have 3 damage burn which is a better spender of your mana.
3. You have very expensive cards that do very little. And on that note let's look at your cards:

The following cards are good: Lightning Bolt, Rift Bolt, Lava Spike, Reverberate. The rest is either too little damage for too much cost (Volcanic fallout, Staggershock and arguably Incinerate) or don't do enough damage for the cost compared to other options (Galvanic Blast since you have no artifacts, Shock, Tarfire).

The goal of a burn deck is to win the game as fast as possible and as efficiently as possible. So when you spend mana to do something you want it to have an impact on the game. Dealing 3 damage to a player for 1 mana does that, that's the best and cheapest damage you can have.

Next you need creatures (because they can stick around for multiple turns and deal more damage for their cost or can have various tactical effects). But if you play a creature you need to have it make a difference immediately, so you need haste (if at all possible). 1 mana for a 3/1 with haste is good. The problem is that that line of creatures (ball lightning, etc) die at the end of turn, so it's not effective. On the other hand a creature like Goblin Guide which is a 2/2 haste creature for 1 mana is very good. You play it and it attacks right away + it doesn't die at end of turn. It also has utility which is important. This is basically the go-to creature for most burn decks. The second creature I recommend is Vexing Devil because it's a 1 mana 4/3 that gives your opponent the choice of either taking 4 damage now and get rid of it or leaving it on the field. It doesn't have haste but it's impact is immediate and even on turn 3-4 it can stay relevant. Either way is good for you. If he takes 4 you just did 4 damage for 1 mana which is perfect. If he leaves it around you now have a 4/3 that can cause some havoc. I wouldn't put any other creature in the deck because most of the others suggested simply don't qualify for a deck that wants to be the fastest around.

I actually posted my own version of the fastest burn deck I currently play last friday. So if you want to work together I'm totally happy to do that.
