Has the Tecumseh been replaced by a Briggs ? it originally came with a Tecumseh , also this model you gave me isn't correct it's the family number ,It's stamped into the engine rewind shroud or on the overhead cover if it's overhead valve .

This mower always had the B&S engine.

Stamped on the shroud is the following:

Model 12V802

Type 1787-B1

Code 00102659

Very strange it has a Briggs , I'm a MTD dealer , when I type in your model it says it's a Tec. lev120 , but thats OK .

Blade -(NNN) NNN-NNNN/p>

Spark plug RJ19LM

Air filter 497725s

Pre filter 273185s

It is quite possible that I do not have the correct Model Number. This was purchased in 2001. With you data base, could you go in and dig out a more probable Model Number?


What size socket does it take to install/remove the spark plug? Is it a metric size?


Which manufacturer goes with the Air Filter and Pre Filter part numbers?

The model you gave me is a 2004 . The spark plug size i 13/16 . Goodluck Robert P
