The Vanguard V-Twin 33 to 35 gross horsepower engine is a small engine designed for use in several different types of power equipment. According to Briggs & Stratton, it can be used in everything from concrete equipment to wood chippers to large commercial-grade lawnmowers. Briggs & Stratton sells the Vanguard V-Twin with, as of November of 2010, a three-year warranty.

Dimensions and Capacities

Measuring 14.92 inches long, 19.53 inches wide and 28.54 inches tall, this Vanguard engine weighs 56.7 Kilogram. It has a 3.5-quart fuel tank and holds 2,300ml of oil.

Engine Design

This Vanguard has two cylinders in a horizontal configuration. Each has a bore of 3.37 inches and a piston stroke of 3.41 inches, and each operates at a compression ratio of 8.2-to-1. The V-Twin's total displacement is 993 cubic centimetres and it can generate between 33 and 35 gross horsepower.

Engine Components

The engine's cylinder block is made of an aluminium alloy, although the sleeves for the cylinders are made of cast iron. It also features a two-barrel carburettor and a multi-stage air cleaner. Ignition is controlled by an electronic system for better performance. In addition, Vanguard uses a number of components, including a specially designed muffler and crankcase, to make this engine run as quietly as possible.


Briggs & Stratton sells this engine with a three-year limited warranty. The warranty applies to both consumer and commercial use and covers both parts and labour.


A number of optional features can be added to the V-Twin. These include a Marine Package for use on the water, as well as different crankshafts, alternators and even the ability to meet the California Air Resources Board's stringent air quality standards.
