Rear Free wheel,s! Whats better to use.
I race BmX and I am just getting opions on what gear set. With 43 teeth sprocket, should i get a 17-20 teeth free wheel or a 14-16 free wheel for more burst in speed? And what do i get for more top end

That is a hard question to answer in this setting. The gearing should be low enough that you can push a good start, but not over revv on straights. I would side on the higher drive ratio. 42x16 is a common gear for mtb singlespeeders, so I would say 43x16 on a bmx would be a good start. Find a person with a similar gear set and take notes.

42x16 on an SS MTB? Are you kidding? My knees would explode. On MTB singlespeeds, you typically run 2:1, or a 36:18, or a 32:16 are the two most common, by far.

Exactly. A BMX will need a higher amplitude than an mtb. 32x16 is a much more versatile gear for mtb, agreed. It depends on what the intended application is, as I said.

The most common BMX gearing is aroud 2.75, ie the front sprocket is 2.75 times the size of the rear one. 43/16 would be on the lowish side, 43/15 on the high side. I'd go for a 43/16 but that's only because decent 15t freewheels are hard to find. But it's all personal preference.
What are you riding? Racers tend to go high and the rest of us stick to regular or low.
Low gear = More acceleration (and more stress)
High Gear = Higher top speed.
