Agreed

So I quickly went and checked, the 45 cc saw has 45f stamped on the cylinder base, the 52 has LW, and the 62 had nothing.
The baumr starter has a 2 piece setup where the inner piece is connected to the cord drum via a spring.
Here's a pic:
I'm not that fat!
So baumr on the left ,standard Chinese right,
The Flywheels are also different.

Whilst doing this I realised I have never even pulled the plug before! Still running the Chinese original.
And here's the different shaped starter cover:

I think I only have the standard cylinder

Do you grind a hole and add another tube or not worry about it

I drilled a hole and added welded in another tube, for looks. You can probably just drill another hole and be fine

More pics of the perla barb,for anyone that's interested... so quite a few little changes,nothing major, top cover has heat shield on it and removable air duct of some sort.
Chain brake setup is somewhat different, and the molding for the alloy housing has been altered as well.
It's not pictured but the tank caps are also of better quality than some others I have, and it also has the double spring recoil setup.
Cheers
