Remove the foam filter and make it moist evenly with a few drops of fuel. If the vehicle will be operated in an area with fine dust, use caster oil instead of fuel. It is important that the foam is only moist to trap dirt and allow air passage. With the foam too wet, limited air can pass through; therefore, limiting engine performance. Finally, make sure the air cleaner boot is securely fastened with a zip-tie. 5 12 FUELLING a b c a. Squeeze the fuel bottle, insert into fuel, and draw fuel into the fuel bottle. Fill car's fuel tank with glow fuel. The fuel used should be methanol based model engine glow fuel (available at hobby shops) with 10% to 30% nitro content and 5% to 18% caster/synthetic oil content for lubrication. 13 PREPARING THE ENGINE FOR STARTING a b c d e f a. To start an engine, first remove the glow plug with the included wrench. If it lights up dimly, then the glow plug igniter is low (and it needs recharging). If it doesn't light up, or the plug element looks distorted, then the glow plug is bad (replace with new one). The glow plug used for this engine can be: Thunder Tiger 9281, McCoy #9 / #59, Novarossi C4S / C5S / C6S, OS #8 / #A3 / #A5, and Picco P6S / P7S. c. f.

Throttle maybe required to be opened momentarily, step 9a (release back to neutral immediately after it starts). Remove the glow plug igniter from engine after engine has started and warmed up. If the engine stops right after the igniter is removed, the carburetor setting is too rich. To unflood an engine, remove the glow plug from engine, flip the car upside down, and pull on the starter to release excess fuel. Then, reinstall the glow plug and repeat the engine starting procedure. 15 ENGINE BREAK-IN For a new engine (break-in setting), the high speed needle needs to be set as rich as possible.
