Porting a Chinese G621 Clone

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

Chris, if you're still on this forum, I bought the same Richmond g621 around the same time as you, in 2011. I have a genuine Redmax 621 and wanted to see how the Chinese quality compared. While originally setting up the saw, I took one look at the bar and chain and tossed them in the junk pile and replaced them with Oregon. A few weeks ago I pulled the saw during a Spring shop reorg. All the stickers had fallen off long ago. I couldn't remember the brand name but while going thru my stack of old bars I found the original Richmond bar which led me to this ancient post. I was amused by the volume of negative feedback. It's been 13 years and this saw has gotten a good amount of work which is evident from the photo I took today. The fuel and oil lines are originals, no leaks. The only things that have worn out have been the Oregon 3/8" chains. I still have the Redmax but I haven't used it since I commissioned this saw.
