The first one or two numbers of the model number of Briggs engines states the cubic inch displacement. Yours, a model 170402 designates a 17 cubic inch displacement. Take the displacement and multiply by .4 and you will have a pretty close guestimate. 17 x .4 = 6.8. You have a 7 horsepower engine. This does not apply to OHV engines or the twin cylinder opposed engines.
