Identification of R/C gas motor.
This is what is on the tag attached to the motor.
USE Engines
Model # 417951
Serial # 005811
I have been unable to find any info on this engine (Googled it to death). It is a gas engine with spark plug and walbro R/C carb. I am trying to get the cc of the motor and any other info that is available. Any information would be great. Thanks Much.

RE: Identification of R/C gas motor.
Take the spark plug out and use a wood dowel or piece of wire to check the total stroke.
Now pull the muffler and check the diameter of the cylinder.
Volume of a cylinder in cc:
radius squared x 3.14 = area of the cylinder
area x stroke = volume
That will give you the engine size in cubic inches.
Take cubic inches x 16.25 and that will give you cc

The area of the cylinder = diameter of the cylinder squared x 3.14 / 4

I never tried diameter x 3.14 / 4
