84’ 200x won’t start
 

I’m having a big problem trying to get my 200x to start. I just freshened the motor up a little, new gaskets, big bore kit(66mm) and high compression piston. I got fuel, I got spark, I got compression. But she just won’t fire at all. Idk if my spark is on the wrong stroke, or if my timing is off. So far, it looks like it’s times right. Please send help
