put a gasket kit in it with a new needle and seat.

Yeah, these belts can seem impossible to figure out. There are idler pulleys that press against the back of the belt. The routing is sometimes not obvious. Do a search for your particular model.

Hi and welcome to FixYa, I am Kelly

After experimenting with numbers I have come to the conclusion that the 2 in your model number is an 8

The domestic engines (Briggs, Tecumseh) take SAE 30 weight motor oil. The import engines (Honday, Kawasaki) usually take 10W30 motor oil. In either case, I recommend using a good quality name brand oil like Castrol, Pennzoil, etc. Most riding mower engine take about 48oz from a complete drain. If your engine has an external filter, it might require a few more ounces.
I hope this helps.

no worries go to searsparts.com type in your model # and follow the prompts you can then print it out for free ?

check the numbers on the motor and you can contact Tecumseh or check their website for info, they are usually very good with their help
