How did you check the jets?

Has it sat for a while? If so (and you didn't add stabil) it's probably got gummed up jets. I'd just replace them. You can replace both for about $10 and it only takes about 10 minutes to change them.

The pilot jet is always the most suspect in a no-start situation.

As DDACT sez, it's very likely to be plugged up. Even if you can see daylight through the pilot, it probably has a coating of gunk inside that diminishes the size of the hole.

The best way to verify that the no-start is a fuel condition is to spray a blast of starter fluid in the carb. That rules out valves, spark, etc.

I just used the air compressor and blew them out and saw daylight reinstalled. So if I use start fluid which side do I spray into the back or the front. Thanks for the help. I will buy new jets.

I've allways just removed the air cleaner and give it a shot then crank it and it should fire off for a couple of seconds and then die back out.
