If, during the break-in process, the pull-starter slips when you try to start

the engine, the one-way bearing and pull-starter shaft may be coated with

excess fuel oil. This can occur because the excess oil in the engine

the pull-starter assembly to ensure that the recoil spring does not uncoil and

Apply slight pressure against the pull-starter to help prevent the recoil spring

from uncoiling. Temporarily secure the pull-starter with a rubber band or tape while cleaning the one-way parts and be very careful

when reassembling the unit.

BREAK-IN TIP - WHY IS MY PULL-STARTER SLIPPING?

STEP 2: FINE TUNING THE ENGINE

After your engine has been broken in, you can set the high and low speed needle valves for optimum engine performance.

Be careful to never lean out the engine too much. Remember that the lubricants for your engine are suspended in the fuel. If you

lean out the fuel mixture too much you will also be lowering the amount of lubricant entering your engine. Less lubricant means

more chance of your engine overheating and possible engine failure.

WARNING ABOUT TUNING YOUR ENGINE

❑ Start the engine and remove the glow starter from the glow plug, then allow the engine to warm up for about 10 seconds.

Always make sure that you run the engine slightly rich - you want to be able to see a faint exhaust trail at all times.

SETTING THE HIGH SPEED NEEDLE VALVE

❑ Start the engine and lean out the high speed needle valve as per the procedures above. Close the throttle until the engine slows

down enough so that the clutch is disengaged and the wheels don’t turn when the XT2 is lifted from the ground. Allow the engine to

idle for about 10-15 seconds.

If the engine just stops running as soon as the throttle is advanced, the

low speed needle valve is too lean and the engine is not getting enough

fuel. With the engine stopped, richen the low speed needle valve about

is normal.

though, that once you run the engine

with increased nitro you may not get

satisfactory results if you decide to

go back to a lower nitro content. Also, if you use fuels

the compression ratio, overheating and erratic running

will likely occur.
