Calling Out The Internet BS

[Vintage Engine Repairs]

I remember when I first started to learn about small engine repair it was a minefield of contradictory info, hopefully this video helps to dispel the many small engine myths going around for those new to the hobby!

I had many people coming up to me at work wanting to buy a new chainsaw bar because of the bluing streak along the rails being told they had burnt it up...had to tell them that was just the heat treating that gets painted over and only shows when the paint starts coming off. Now if the rails were lop-sided or burring out to badly or gouged in spots, the I might recommend a new bar if those things could not be corrected.

Same as bluing on the crank.

Same as bluing on the crank.

As in they are -NOT- blued from any kind of heat treating.

What is the difference in bar rail hardness between a painted bar and a natural finish bar?

Asking the same question in a different manner.

Why are the rails on a painted bar heat treated and not a natural finished bar?

Just polished off I guess same as any heat mark.
