Try starter fluid to determine whether its a fuel problem or spark. Remove air filter cover and filter and spray a short burst (about 1 second) of fluid into carb throat (or as close as possible behind baffle C) and promptly pull starter cord.
If engine fires and runs for a second or two then its a fuel/choke problem (compression is ok). If doesn't run, then more likely no spark but could still be a fuel or compression issue.

When you pull the bowl off of your carb is it clean? If not you have some contamination possibly inside. You might want to remove the carb and blow compressed air through all the vents a ports.

Sounds like it may be drawing air around the intake somewhere. Let it idle and spray around carefully with wd-40 until it speeds up. This will reveal the leak.

I would be checking for air leaks, this will give you a lean mixture. In particular look for the seals for the balance tubes and each carb.

I believe that Toro Guarantees to start 1 Pull, was gas left in it all winter?, If so this is'nt covered under warranty, cause gas is to be ran out or dumped out at end of season this will prevent any gumming up of carb . did you completely disassemble carb? does it have a primer on it, those gskts need replacing, clean out the jet in bottum of float bowl,small holes,sometimes missed and remove and check your needle/seat to make sure that when float drops gas runs out then lift float up and gas should stop. hope this helped you,another thing spray carb cleaner in carb and pull over and see if it will start that way enough to keep running with choke to see if it will **** gas into it

Hello, I think i can help you.
It appears you have a clogged or partially clogged carburetor". What you can do is tip the mower on it's left
side, remove the air filter and just spray carb cleaner into the
carburetor without removing the carb. It is common for a blade
of grass to get in there and clog it. The pressure from the carb spray
will usually dislodge a blade of grass. Try not to remove air cleaner assembly unless necessary. They can warp
easily and once you remove them, they rarely go back on cleanly ie
without leaking, and you'll need to replace it. Also, if it's not too
dirty, just adding Sea foam to your fuel can be very effective. For the
$10 cost of a can of carb cleaner and a can of Sea foam, this worked for
me. ANother area to check, and cheap to replace, is the spark plug. I automatically ever year, replace spark plug, change oil, put new air filter in ( which you did already) and always make sure you put fresh gas in. Another note; Sometimes it will get a vapor lock where the fuel cap is, loosen some pull a couple times and then tighten down. If your toro has fuel filter , positively replace that.
Conclusion, I believe your problem lies in the carb needs to be cleaned and make sure fuel filter is replaced if this unit has one. Please let me know if this helps, if not we will go from there. Thanks Mike, from Fixya.
