Maybe see if you are getting spark? Remove the plug, ground the base, put the cap back on & pull hard. You should see a blue/white spark across the gap. If you have good spark, squirt a little bit of gas in the plug hole, put the plug back in, pull hard and you should get a pop or partial run for a few seconds.

If that happens, it is likely that the carb needs a thorough cleaning. Once you get it running, suggest you drain the float bowl if you aren't going to use it in a week or so.

All this assumes the tank is venting properly and that your primer bulb is getting fuel to the float bowl. You can loosen the drain screw on the carb to see if gas flows out when you squeeze the bulb.
