3.3 CARBURETOR ADJUSTMENT GUIDE ( L ) LOW SPEED FUEL MIXTURE ( H ) HIGH SPEED FUEL MIXTURE ( I ) THROTTLE SPEED SCREW 1 T.O. RICH LEAN ¼ ¾ T.O. T.O. ½ T.O. T.O. = TURNS OPEN Normally the correct setting of the mixture screws, after engine run-in, is the following: L (close the screw completely and then open): 1 T.O.
3.4 STARTING AND STOPPING THE ENGINE Starting is achieved by the starting key. This is a 3 position key: 1- STOP (key can be removed) 2- KEY 3- RUN In STOP position the battery is disconnected and the engine stop signal is sent to the electronic box.
3.5 ENGINE BREAK-IN The break-in of the engine must be performed following a few fundamental rules: 1. Adjust the carburetion. Start with an adjustment on the rich side. 2. Warm the engine gradually for about 5 minutes at half throttle, making some laps at low speed, gently closing and opening the carb.

3.8 EXHAUST SYSTEM Before every test, make sure that the flexible is not damaged. Replace if necessary. ATTENTION: In case the flexible is damaged, metallic particles could be sucked in the engine and cause a seizure. Always make sure that the springs are well hooked and in place. In case of breakage, replace the broken spring.
Page 29
3.9 BATTERY The battery (12 V – 9 Ah) is sealed and without maintenance. In order to lenghten the battery life it is necessary though to follow a few recommendations: When the tension drops below 12.6V. It is necessary to recharge the battery. Max.
Only use 5A strip fuse. Use of fuses with higher amperage might damage the electronic box whenever the battery polarity is reversed. 12) Only use sealed lead type batteries as specified by IAME. Only use 12V. batteries. 13) Always disconnect the battery from the electrical system when recharging the battery with an external battery charger, otherwise the internal voltage regulator could be damaged.
3.11 SPARK PLUG AND THERMAL DEGREE The engine is supplied with a standard NGK BR10EG spark plug, which represents a good compromise between the needs of a good break-in and the racing needs in normal conditions. Use of different spark plugs is possible and, as a general information, we are attaching a correspondence list among spark plug of other brands, based on thermal degree which represents the capacity of the spark plug to dissipate the internal heat.
Page 32
According to the different engine versions. ATTENTION: Never exceed the above limit. No obligation of IAME exists in case the above limit is exceeded. In case the user wishes to optimize on the track the sprocket ratio in order to achieve the best possible performance, without abusing the engine, follow the under shown recommendations.
Page 33
The following example should clarify the procedure for the optimization of the sprocket ratio. Assume to use the engine with Z=10 teeth engine sprocket and that during the preliminary track tests a Z= 77 teeth axle sprocket has been used. From Table 1 with Z=10 as engine sprocket and Z= 77 on the axle sprocket, a ratio of 7.70 is found.
Section 4 - BASIC MAINTENANCE 4.1 CENTRIFUGAL CLUTCH The engine has a low maintenance dry centrifugal clutch. The following prescriptions, if carefully followed, will allow a long clutch life. When starting the engine, make sure that the brake pedal is fully pressed to avoid sudden accelerations.
Page 36
4.2 INSTRUCTIONS FOR THE DISASSEMBLY/ASSEMBLY OF THE CLUTCH ATTENTION: the following operations can be performed by a skilled mechanic, under the conditions to have available the dedicated tools shown on the text, otherwise it is necessary to apply to an Authorized Service Center. Refer to the following drawing during the operations.
Before assembling the clutch, wash with diluent the shaft taper, the connecting hole on the clutch body, the clutch drum and the starter ring. Install clutch 1. Install the starter ring on the clutch body by matching 12 point wrench 10 mm the three holes and the dragging pin (3 screws M6).
