ABSTRACT:
An integral plastic engine housing is disclosed for small internal combustion engines such as those used on lawnmowers, snowblowers, generators and the like. The integral plastic housing integrates the blower housing, air filter housing, fuel tank, starter rewind housing, carburetor, primer bulb assembly and brake cover into a single unit to reduce the manufacturing and assembly costs. In a preferred embodiment, a plastic carburetor is connected to the remainder of the integral plastic housing via a pair of rails and corresponding slide members. The position of the carburetor with respect to the fuel tank and the air filter housing allows the air filter housing and fuel tank to be directly connected to the carburetor without the need for intervening hoses or lines and their associated clamps. The integral housing is substantially made from a polyethylene plastic material, with the carburetor and parts of the primer bulb assembly being preferably made from nylon.
