Sold Is this a "Clamshell"?

[Pepster]

Bought this Craftsman 55cc saw well over 10 years ago BRAND NEW.
POS used it twice & the rear handle cracked & broke in short order...
Made by Jenn Feng (Taiwan).

Believe it or not, the cylinder/piston are pretty well made.
C-clips are tiny.

It's like a "Hybrid".
Husqvarna bought "Jenn Feng".

Is this considered a "Clam Shell"?

Don’t think so. To my knowledge a clamshell top end bolts around the crankshaft.

It looks like one to me. The cylinder bolts to the isolation block and the isolation block bolts to the crankcase.

I'm gonna find a little 33cc/14" bar saw & fit this 55cc engine in...
Just for fun.

It's like new & ran decent the two times I ran it.
Back then I thought it had some power. LOL!

This is a true clamshell

What little research I've done, the Husqvarna 350 is very similar in design.
Considered a clamshell with the benefit of removing the gasket between the crank block & jug.
Thus increasing compression.
