Default RE: ringed engine break in?


ORIGINAL: skiman762

enough of the armature hour I am going over to the manufactures forum
and ask the question there lets see what kind of answer we get from them
think I'll start with YS since I have one and they say run rich for break-in
I was refering to piston rings, not armatures.

Let's look at the YS manual, shall we ?

3. "the needle valve should be set so that the engine in running at a rich setting".

Gosh willikers....that's what I said too, Remember I said to set the engine at 500 RPM down from full peak. That is a rich seting.

YS: "run the engine for 20 minutes at this setting"

WOW !!....what a coincidence....that's what I said. Run the engine for 20
minutes to complete the ground break-in.

Keep in mind, the original Members post was in reference to a GMS 1.20 engine.
You are now changing horses in the middle of a stream to 4-cycle engines.

I get my references from a lifetime of experience, not from the Internet.
I do read the operators manuals, and I still have the manual for every new
engine I have purchased.
