Yamah blaster won't start

[MOPAR ty]

I just rebuilt my top end and broke it in. After I rode it for the first time I shut it off. When I went to start it again it wouldn't start. It doesn't seem to be getting spark even though I just replaced the ignition coil and spark plug.

Check the kill switch.

I checked the kill switch but that's not it

Try unplugging the key switch and starting it. It is 2 plugs right at the ignition. Check your grounds also...

I don't have the key part on my quad

Is it getting spark at the spark plug?
Put the blaster somewhere dark, remove the spark plug, touch the threads on the spark plug somewhere to ground it (with the wire attached)...usually the head, and kick it over by hand and look for spark.

Already did that no spark

I fixed the spark problem but I don't think it is getting enough gas. I have a 67.25 piston, what size jet should I put in it.

piston/bore size has no effect on jetting.

pull and clean carb
check reeds

Set the float level.
