Sears 5.5 HP self propelled mower

I have a Sears 5.5 self propelled mower with a Techumseh engine on it. I don't have the model number because Sears only put their stock number on it. It is 143.945504. I have deduced that this is a Techumseh because of the carb on it. The problem is when I start it, it will run for about 2 seconds and die. I have taken the carb off and cleaned it. I have not put a carb kit in, because it looks good, so What else could be the problem? Thanks in advance.

The bowl nut(main jet) has from 0 to 4 holes in it and the one at the top, almost invisible on some, is usually the problem, I use the wire from a twist tie to clean it. Use the picture below for reference only as there are several types. Have a good one. Geo
