You can cross reference a RC12PYP3 or RC12YC non-platinum spark plug for a Briggs 696798. The Briggs Platinum 696798 spark plug is for a snow blower. Part number 696020 for a Platinum plug from Sears is an equivalent also.
Take off the gas cap. Take off the big plastic cover with a socket and wrench.Then put the gas cap back on. Then pull of the spark plug boot. Then take off the spark plug with a spark plug socket and wrench. It should be 13/16" socket with 3/8" drive wrench. I Think the spark plug gap is 0.025 but you would have to look at a manual.
I will assume a valve-in-block engine and the answer is an RJ19LM Champion or equivalent.
If a snow blower is not getting gas, there could be a few different problems. The fuel line could be clogged, or the spark plug might have gone bad. There could also be a hole in the fuel line.
13/16" - at least that is the size for my honda 520S snow blower.
