The following procedure is recommended for this engine when the ProTek R/C P3,
PTK-2060 or PTK-2090 tuned pipe and fuel containing up to 30% nitromethane are used.
• Identify and note the flywheel position when the piston is at Bottom Dead Center (BDC).
• Fill the tank completely with fuel.
• Check the glow plug and verify that the filament glows bright red when the igniter is attached.
The carburetor is set at the factory as shown in the images below. Double check the
settings before you start the engine.
• The high speed needle (needle valve) is set approximately 3-turns open from the fully
closed position.
• Idle gap is set approximately 0.5mm open.
• The opening should be approximately 0.5mm with the restrictor removed.

• Low speed needle (metering needle) and mid needle (mixture control valve) are set at the
basic position (refer to P23).
• Switch the transmitter on and make sure that the linkage moves correctly.
• Pre-heat the engine to approximately 150°-160°F (66º-71°C) using an engine heater or heat
gun before starting.
• Plug the stinger on the exhaust and
turn the engine over with the starter
box to draw fuel into the engine.
• Now connect the glow plug igniter to
heat the plug and start the engine.
If the engine does not start, or
stalls out right after started, try
the following:
Set the high speed needle approximately 2.5 turns open from the fully closed position. Do
not force the high speed needle to turn beyond a lightly closed position.
Set the throttle opening a little wider than the factory setting by adjusting the idle screw
(throttle stop screw).
• When the engine starts, warm it up using smooth throttle inputs, increasing the rpm to
medium speed and back to a fast idle in the neutral position with the mixture set rich.
Leave the glow plug igniter connected, and keep the wheels of the car off the ground.
The slightly rich mixture will provide adequate lubrication and cooling indicated by profuse
exhaust smoke.
