The carburetor has the number stamped on the underneath.

I'de think just knowing the make and model would be enough. Most mod and sn i've seen would be on the engine block itself. Usally it's stamped near the base on the side and it's pretty obvious as they mold a chunk and shine it before it's stamped in and might be covered in grass and oil or whatever. If it's not there then take top shroud and look undernieth it as it might be there or on the block under the shroud too. They make it easy usally and when you take the shroud off don't worry nothings going to fly out like springs and crap.

you need compression to get fuel tho, if you have cleaned the carb, do you have compression,25psi min on 1st pull, 50psi min on three pulls. old mower's you could feel the primer working, newer mower's it is hard to tell it working, plus once u spray carb cleaner the mower should stay running, and once it runs for a min or two, you shouldn't need to use the primer. so if once it starts and wont stay running, it is deffinetley not yr primer. if you take the screw/bolt of bottom of carb and u get gas it is either the passage's are still plugged or u have no compression to pull it through your carb, the passage for fuel through the carb for start an idle position does not get n carb threw the main passage, on older alumin carbs they go threw the side, and on plastic bowl carbs the little tiny brass hole next to the middle(main) on n the bowl, which if u have a plastic bowl, just replace it, yr not going to get it unplugged. but again if the start passage was plugged once u sprayed carb cleaner to start it, it should stay running, so u have a plugged main jet or no or not enough compression. one other though, did u hit somthing latley, ck yr blade for a big nick, or if u have a tree stump, u may have sheared yr flywheel key, which will show spark and confuse u thinking its the carb??

Watch this video, it will show you what to look for. You need the engine numbers to get the carburetor kit.

You may be able to order the kit by the brand and serial number of the carburetor.
