Is suppose to have a 6 turn air inductor connected on each side of the 33p cap but when I put a regular inductor there it does something weird and a antenna wire coming from the 10p and suppose to have a mic on the fastest left bottom side bit no mic option wondering and trying to figure out why my FM transmitter isn't working at help would be awesome

Too dirty approach. This is also a considerably simple FM Transmitter, and requires careful consideration when built, and still has some frequency instabilities. Best approach is PLL, but that's way more complex. http://everycircuit.com/circuit/6350493573185536
