Uncompress the spring about 3/16"(4. 5mm) by sliding the collar back and then tighten the setscrew. Repeat step13d with the forward collar. 8 14 a d ADJUSTING CARBURETOR b c e a. To set the high speed needle (large needle sticking out from the carburetor body), turn the screw as pictured. Initial high speed needle setting should be 2. 5 turns (close the needle completely, then back out 2. 5 turns). Clockwise turn will provide leaner setting (lower fuel to air mixture), and counterclockwise turn will provide richer setting (higher fuel to air mixture). To set the carburetor idle (small needle sticking out from the carburetor body), turn the screw as pictured. Do not use airplane or boat fuels in your truck. Choose methanol based model engine glow fuel that has a nitro content in the range 10%-30% and 5% to 18% caster/synthetic oil content for lubrication. Lower nitro percentages will generally result in a cooler engine running temperature and therefore last longer before needing a rebuild; cooler-running engines also generally produce less power. 20% nitro is the most widely used fuel in these engines. Fuel color is for identification purpose only and is not important to performance or durability of your engine. 16 a PREPARING THE ENGINE b c a. To start an engine, first remove the glow plug. Prime the carburetor by squeezing the primer bulb while watching the fuel come through the line and just reach the carburetor inlet. Then, give the bulb another 1/4 squeeze(1/8thinch). BE CAREFUL NOT TO SQUEEZE TOO MUCH or the engine will become flooded. Attempting to start a grossly flooded (or hydro-locked) engine (full of fuel) can cause serious damage to internal engine parts. c. Check the glow plug by plugging it into the glow plug igniter. The glow plug element should light up brightly. If it lights up dimly, then the glow plug igniter is low (and it needs recharging). If it does not light up or the plug element looks distorted, then the glow plug is bad (replace with new one). [. . . ] Setting the slipper too loose may result in a damaged spur gear. Loosen Slipper Clutch Tighten Slipper Clutch 13 Shock Springs Stiffer springs will give you better handling and higher cornering speed on smooth surfaces such as asphalt, concrete, and hard pack dirt. Soft springs are better for rougher terrain, rock crawling and jumping. Softer springs will increase the rollover tendency of the truck at higher speeds.
