GENERAL DESCRIPTION OF THE ENGINE
This engine of the "TaG" series (Touch and Go) has been expressly designed and
developed for the powering of karts for hobby racing on closed tracks, destined for this
specific purpose. When designing this new line of engines, the technical solutions already
adopted for the high performance engines were used, in order to guarantee the highest
reliability of components, when the operating limitations are respected.
The motor is a single cylinder using the two stroke principle.
The cylinder and the crankcase are in aluminium alloy.
The pressed in liner is made of centrifugated cast iron, fully machined to guarantee the
best possible stability.
The head is separated from the cylinder and secured by studs.
The crankshaft is built and supported by two ballbearings. The crankshaft is of steel alloy,
hardened and tempered , as is the connecting rod which runs on roller bearings.
The digital ignition with capacitive discharge is fed by a magneto which generates the
spark energy for the starting of the engine, supplies the advance timing through an
integrated pickup and recharges the battery.
The ignition includes a digital electronic unit (powerpack), the statorrotor, the starter
relay, the H.T. coil, a switch key assembly, and the wiring harness (with a 5A fuse) which
connects the whole system.
The electronic box which controls the advance, the rev. limitation and the engine start/stop
logic , integrates the voltage regulator and the ignition circuit.
The starter relay (Solid type SSR), protected from shortcircuits, supplies the power for the
electric starter and is controlled by the power pack.
An RPM limiter, integrated in the power pack, prevents the engine from exceeding 17000
RPM during use.
The spark is generated also without a battery; it is therefore possible, in case of
emergency, to start the engine with an external starter unit.
With the starter key in “RUN” position, the starter activates a Bendix type gear which
engages the starter ring assembled on the clutch.
The engine is provided with an automatic dry centrifugal clutch with low maintenance and
with interchangeable sprocket.
The carburetor is a diaphragm Tillotson carburetor with integral fuel pump, filter and all
position mounting capability.
The battery (12 V 9Ah) is a sealed, no maintenance battery and is supplied already
preassembled, in the battery support box which can be easily adapted to all existing
chassis.
The exhaust, included in the supply, is already tuned for the best possible performance.
The engine is supplied with a kit which includes the radiator, the pump, water hoses and
whatever necessary for the assembly on the kart.
