1 SUPERTIGREINSTRUCTIONSG-34 to G-2300 Entire Contents Copyright 2003 SUPZ1000 Important:Please read and follow this instruction manual beforeoperating your engine. These instructions have been written so that youmay get the greatest satisfaction from the operation of your SuperTigreengine. All SUPERTIGRE engines are designed for outstandingperformance, and are manufactured with the latest computer-controlledmachinery to insure their high quality. SUPERTIGRE engines haveappeared worldwide in competitions from local club events to WorldChampionship :The crankshaft transforms the reciprocating motion of thepiston into rotational motion.

2 The propeller is mounted on the portion ofthe crankshaft protruding from the crankcase. The portion of thecrankshaft protruding past the drive washer is known as the prop shaft. Basic Engine Parts2 Propeller Nut:The propeller nut secures the propeller to the Washer:The propeller washer provides a larger, strongersurface area to apply pressure to the Washer:The drive washer is secured to the crankshaft with a lockcone and is knurled on one face to provide a non-slip contact surface forthe :The carburetor controls the amount of fuel and air thatenters the :The crankcase is the main body of the engine whichhouses the internal Head:The cylinder head is mounted on top of the provides a seal at the top of the cylinder.

3 The fins on the cylinder headprovide a cooling surface. The cylinder head also holds the glow Plug:The glow plug provides the heat needed to ignite the fuel inthe Manifold:The exhaust manifold allows the adjustment of thedistance from the muffler to the :The muffler quiets the exhaust after it exits the Fitting:Allows air pressure from the exhaust system topressurize the fuel Speed Needle:The high speed needle controls the amount of fuelentering the carburetor during medium and high speed Mixture Screw:The idle mixture screw controls the amount of fuelentering the carburetor while the engine is Stop Screw:The idle stop screw controls how far the throttle barrelcloses.

4 We suggest that it be set to allow the throttle barrel to closecompletely to enable stopping the engine by the throttle trim on Arm:The throttle arm is connected to the carburetor barrel. Bymoving the throttle arm, the barrel is opened and closed. This regulatesthe speed of the Carburetor Parts4 First insert the carburetor retaining bolt (the bolt has a curved arearemoved from its center) into the hole in back of the carburetor the retaining bolt so that the removed area in the bolt matchesthe curve of the carburetor opening. Install the split washer and the nuton the threaded end of the bolt. Insert the carburetor in the carburetoropening and press down on the carburetor while tightening the nutmaking sure the O-ring is tightly sandwiched between the carb Installation5 Retaining BoltThe beams on which the engine is to be mounted must be rigid, parallelwith each other, and the top surface in the same plane.

5 Set the engineon the beams at the correct angle to the centerline of the fuselage,according to the instructions provided by the airplane Installation6 When the engine is mounted in the upright position, the centerline of thefuel tank should be at the same level as the high speed needle, or nomore than 3/8" lower, to insure proper fuel flow. When the engine ismounted on its side, the centerline of the fuel tank should be at thesame level as the center of the intake in the carburetor, or no more than3/8" lower, to insure proper fuel flow. Most airplane kits have this fueltank position built into on the engine mounting beams the locations of the four mountingholes.

6 If mounting the engine on wooden beams, drill four 7/64" holes forthe .34 to .51 size engine (or 11/64" holes for the .61 to G-2300 sizeengines) through the beams perpendicular to the top surface of thebeams. Secure the engine to the beams with 4-40 screws, flat washers,lock washers and 4-40 nylock nuts for the .34 to .51 engines (or 6-32screws, flat washers, lock washers and 6-32 nylock nuts for the .61 toG-2300 engines).7If mounting the engine on a metal or fiberglass engine mount, drill andtap the engine mount to accept 4-40 screws and lock washers for to .51 engines (or 6-32 screws and lock washers for the .61 to G-2300engines), installed through the engine mounting flanges and into theengine :Some airplane kits require a slight amount of right thrust.

7 Sometimesthis is done by angling the engine to the right to counteract the torquefactor of the propeller. Follow the kit manufacturer s instructions toincorporate the correct amount of right thrust, if the two supplied screws, split washers and nuts to attach theexhaust manifold to the engine. Make sure to install the gasket betweenthe manifold and the engine and tighten the screws Installation8 Install the 4mm x 7mm screw, split washer and 4mm nut in the muffler,but do not tighten. Slide the muffler over the exhaust manifold andposition it so that it does not touch the fuselage. Also, to reduce drag itis best to position the muffler parallel to the fuselage.

8 When the muffleris positioned correctly, tighten the 4mm x 7mm screw to clamp themuffler over the exhaust the engine to operate properly at any flight attitude, the carburetorrequires constant fuel pressure. When the engine is running, pressurePressure Line Installation9is created in the muffler by the exhaust. Some of this pressure is usedto pressurize the fuel tank. This pressure is provided by a tube from thepressure fitting on the muffler to the vent tube in the fuel tank. Althoughnot absolutely necessary, pressurizing the fuel tank with mufflerpressure will provide more consistent running, and will help to maintainmore consistent fuel flow during maneuvers.

9 To install the pressurefitting, remove the screw in the side of the muffler. Install the gasketwasher on the threaded end of the pressure fitting. Screw the pressurefitting into the threaded hole in the a medium size (3/32") silicone fuel line from the fuel inlet on thecarburetor to the fuel pick-up tube that is connected to the clunk in thefuel tank. We suggest that a fuel filter be installed in the fuel linebetween the carburetor and the fuel tank. The filter will prevent anycontaminants in the fuel from clogging the carburetor, or damaging theengine Line Installation10 High Quality Fuel:The recommended fuel for your SUPERTIGRE engineshould contain a minimum of 18% - 20% oil (either Castor oil, Syntheticoil, or a blend of the two), 0%-15% nitromethane and the balanceMethanol.

10 Almost all of the fuels on the hobby market with between 0%and 15% Nitro content will be fine, but you may get better results froma Premium fuel as opposed to a Sport fuel. Higher levels ofnitromethane may require adjustment of the compression ratio toprevent detonation. Check with your hobby dealer to see what fuels arepopular in your Pump:We recommend an electric fuel pump that can be operatedfrom a 12V battery. If you do not have a 12V battery, we recommend ahand operated fuel :Choose a propeller for initial running from the heading Break-In from the chart listed in the Initial Setup Stick or Electric Starter:We recommend an electric starterthat can be operated from a 12V battery.
