This series of engines are usually to be found on ride-on lawnmowers and garden tractors.
They have the two cylinders opposite each other in line, with the spark plugs fitted fairly centrally on each side of the engine.
The air filter is an oval cartridge type filter inside a metal cannister at the front of the engine. The carburettor is below the air filter cannister and mounted on cast manifold that runs across the front of the engine. The fuel pump is fitted directly to the front of the carburettor.
The Model, Type and Code numbers are stamped either into the pressed steel cowling just above one of the spark plugs or on a small alluminium plate rivited to the top of the cowling. The Model begins with either 40 or 42
Notice of possible service disruption
Between the last week of June and the first two weeks of July, Briggs and Stratton will be implementing a global update of all systems. During this period, there will be no movements of parts or engines from their distribution centres. This will impact on our service to customers. In readiness for this, we are endeavouring to increase our stocks in line with anticipated sales over this period however, it is inevitable that some items will become out of stock due to unexpected sales trends. Similarly, many less popular parts ordered through the special orders system which we do not hold here, will experience a fairly substantial delay. We are already noticing some disruption in parts movement as Briggs prepare for this monumental change. We shall endeavour to keep customers informed where we become aware of any orders or enquiries for parts affected. Some anticipated availability times will no doubt be somewhat disappointing but we will try to be realistic rather than promising something that is unlikely or unachievable.
All being well the disruption will be kept to a minimum and our increased stock holdings will largely allow the majority of regular orders to be processed as normal. Apologies in advance for any inconvenience that this may cause
