OS GT22 Petrol with E-5040 Muffler L-OS38200
Bringing OS petrol engine technology into the smaller class of model, the OS GT-22 has the high quality that you would expect from OS in a compact, powerful package.
Like the GT-33, the GT-22 has a steel liner for durabilty, a lightweight, ringed piston and a one piece crankcase. OS have optimised the internal design in a way that allows performance combined with easy starting and durability. Deep fins are needed to carry away the extra heat generated by petrol engines.
Internally, OS have used a special design of aluminium conrod with pre-installed roller bearings. Using aluminium instead of steel like many of the strimmer based engines means reduced reciprocating mass. This in turn means reduced crankshaft counter-balance. Not only does it reduce weight overall, it also allows quicker throttle response, higher RPM and reduced vibration.
Carburation come courtesy of a Walbro carburettor adapted for the GT-22. Being a pumped style of carburettor, tank height and location is less critical than a non-pumped carburettor. Once set for the fuel being used, it requires almost no adjustment.
Ignition is provided by a sophisticated unit that is also common to the GT-33. The main HT lead is shielded to prevent interference and the spark is delivered by a high quality CM-6 spark plug.
