GENERAL REFERENCE

Standard Bolt Torque Specification

Fuel / Oil Premix Ratios

Formula:

• 1 Gallon = 128 Ounces

• 128 / (Desired Ratio) = Ounces of oil for every 1

gallon of fuel.

• 128 / 40 (40:1 Ratio) = 3.2 ounces of oil for every 1

gallon of fuel.

Always mix ratio in 5 gallon increments.

NOTE: A 40:1 premix should always be used during
engine break-in or after re-building the engine.

Gasoline Volatility

When gasoline is blended, it is given a Reid Vapor
Pressure (RVP) number which reflects its ability to
vaporize or mix with air at a given temperature range.
Gasoline vapor pressure is measured by putting a sample
of fuel inside a closed container and applying a specified
amount of heat to the container for a certain amount of
time. RVP will vary from about 7.0 PSI during the summer
to approximately 13.5 PSI during the colder months.
Service stations selling a large volume of fuel will normally
have the correct blend to work well at all times throughout
the year in their local area.

When the weather is very cold, gasoline must be able to
vaporize very quickly in order for an engine to start and
warm up properly. If summer blend fuel is being used in the
winter, little or no vaporization will occur. Droplets will form
causing flooding and very hard starting.

If winter blend fuel is being used during the summer
months, it may cause vapor lock (boiling fuel) inside the
fuel lines, fuel pump, or carburetor. This will cause warm
engine driveability problems and hard starting when
warm.

Piston Wash / Spark Plug Reading

Changing temperature, barometer, altitude, and fuel
supply are just a few of the factors that can affect the day
to day performance of your engine. That is why using
Exhaust Gas Temperatures (EGT) are important for
maintaining optimum performance. There are two
methods for helping you determine what the EGTs are for
your machine. Piston wash and the coloring of your spark
plug. The piston wash is by far the most valuable tool in
concluding EGTs, with the spark plug color running a
distant second. Use the illustrations below to help
establish the EGTs for your machine.

Once the proper jetting is established, you can reference
the EGT gauge for your baseline numbers. Then, if there
is a rise or fall of 25 degrees, you must jet accordingly to
return your EGTs to the baseline numbers.
