CARBURETOR SETTINGS BREAKING IN THE ENGINE To insure long life and good performance from your Torq .21 engine, you MUST break-in the engine. The break-in period is critical for long life of the internal parts of the engine. This should be done over the first 5 or 6 tanks of fuel. Be sure to watch the engine tuning video that came with this kit. Some Things To Remember During Break-In: 1. Run with the body off. This will keep the engine cooler. 2. Keep the air cleaner on at ALL times. 3.
5. After a minute or two of running, make sure the engine is not overheating by putting a drop of water on the cylinder head and watching it boil away. If it boils away within 10 seconds, stop the engine and allow it to cool. Open the high-speed needle around a 1/4 turn before starting again. This is a good habit to get into every time you run to ensure that the engine does not overheat during any run.
8. Do not scratch the piston or cylinder sleeve. Avoid jamming something into the exhaust port when removing or re-installing the clutch or flywheel. Use a special tool called a crankshaft locking tool, which is installed in the glow plug hole. 9. Do not use silicone sealer on the engine joints. Silicone sealer contains acetic acid, which is corrosive if it gets inside your engine. 10. Do not allow any water inside the engine.
expense of steering response and the car will tend to roll more. In general, shock oils between 20 and 40 weight will be best for your buggy. You should experiment some to see what oils work best for your track and driving style. Shock springs affect the rate that the suspension rebounds from a bump. We have supplied soft springs that work under most conditions. Pre-load on the springs means that the springs are already compressed some so that the suspension will rebound faster.
ENGINE TROUBLE SHOOTING The engine starts It should be ready to go. Clear the engine YES of fuel. Is the high speed needle setting 1 to 1-1/2 turns out from closed (if the engine is broken-in?) YES Does it run continuously? NO YES Is fuel getting to the engine? YES NO Does the engine quit when the glow plug clip is removed? YES Replace the glow plug. NO NO Check for clogging in the carburetor or fuel line. Press the primer pump and check for fuel spraying out of the fuel line.
