Is this the G450 cylinder?

 

[nenicu]

No. The 4 port is 45,2 mm [58 cc chainsaw with 34 mm stroke] and the other is 48 mm [ Fuxtec 62 cc 48x34]. I was comparing the shape of the fins and the transfer ports. The 48mm jug has little transfers and the exterior is smaller than the other.

New McCulloch chainsaw on Ebay.de: strato chainsaw based on Zenoah GZ 4000. On Ebay.de the listing nr 262830957623, McCulloch kettensage CS 35 S. Maybe 35 cc.

Hello Nathan Lassley. Can you post some pictures of the Ryobi 3716 ? Just curios to see iside the carb compartment. Thanks.

Thanks. The cylinder is the low emission type. For 16-17 bucks you can get a low emission 40 cc jug or a 37 cc with transfers like the original[Redmax g3800] on Aliexpress.

You got the cat out of the bag?

 

[TBS]

The cat has disappeared, I've got a 40cc jug from the earthquake.

Here's the cylinder from my surpass tool 56cc.

 

[nenicu]

The bore should be 45 mm for 56cc. The 58 cc are 45,2. For better transfer flow you can get a Redmax g5000 piston with open sides, if you got full skirt piston.

It's a genuine "Huayi" carb! It's an HDA copy.

Thank you chris. I'm trying to get some ideas on for future projects when I get the tanaka done.

Interesting.
This is the new Ryobi we get here:

It's marketed as a 51cc with something called "Full Crank PoWR XT" which is... I have no idea. The Ryobi website doesn't help me and as the saw is so new I haven't seen any yet, let alone dissected one.
Anyone knows what is it could be based upon? I am leaning towards one of the latest Zenoah-based Chinese saws but I honestly have no clue.
