How to tell difference between 2.6 and 3.2 sachs motors. By looking at them.

.

The casting numbers are 44 ZN 18 W4

That's a 3.2 Sachs.
Sachs casting numbers (if it is a Mahle cylinder) are:
40 - 2.6 ci
44 - 3.2 ci
47 - 3.7 ci
49 - 4.2 ci

Thanks that what I was told it was wanted to confirm it.

Hello

How do i tell if it is a true 3.7 ?
The # on the cyl. is a 057/2A
It use to fly me Byron Pitts (it was a lead balloon)
I want to use it for my Ziroli AT6

i may be able to help train you since I've been an old fart for years. Anyhow I need a muffler for my Sachs 3.2 Any idea where I can get one?

Bisson Mufflers, J&A Engineering, and J-Tec. Look for a muffler for a Brison, Fox, Taurus, and First Place engine in your displacement.
