Please help needed 038 …..?

Asking a few questions concerning originality. I’ll attach pictures that match the things that are puzzling me and my search of information is not coming up as definitive to model/year. Sticker = model ..cylinder says and measures 52mm..carburetor only states stihl. linkage fits perfectly and operates flawlessly but wrong side and h/l and idol upside down. Original mahle cylinder/piston all magnesium handle.

Answering my own question. Just discovered the faint outline of super on top badge. So a 52mm ported mahle cylinder matched piston in a super frame. What model is this carburetor? Seems larger, no room for securing nuts. Used filter nuts to secure? Not sure as parts were missing.

Yeah, that's a modified saw. The carburetor looks to be a WJ, maybe from a Husqvarna application or early 064/066. It looks like the builder added a pulse nipple to the fuel pump cover. Some close-up shots of the inside of the cylinder would be interesting.

Yes, they're likely using the air filter nuts to hold the carb and everything in place.

Ordered cylinder/piston. As well as a few other starting parts. Would you think keeping and mimic original build the way to go or go back to 72cc with carburetor to fit.

If the larger carb works and makes a runner, it should be ok. The stock carb is pretty choked down but the 038 was designed to be more of a tractor saw rather than a high-winder, similar to the Echo CS-8000. In stock form they have pretty good torque with the smaller carb.

The "Stihl" stamped on the one cover makes me suspect the carb came from the latter application. What's your take on the massive base cut, quad finger setup, and beveled piston edges? Major woods port or competition setup?

Did you buy that from the Facebook?

It's something funky alright - The recipe doesn't really make sense to me, especially with those sloppy fingers reaching up alongside the exhaust. It looks like the work of two different people. The 038s I've rebuilt wouldn't have needed much of a base cut since they had tight squish clearances and exhaust timing that was pretty good in stock form.

I think somebody did a decent woods port on it initially and then someone else went back into to get more out of it. It's a Canadian saw, so anything is possible.

No in a dark corner in wife’s family cabin last year. A super 797 entered my life a week later and I was hooked on McCulloch. My brother picked up a 028super from a garage sale for $20 just needing an intake boot. So while revisiting stihl I thought I would work this out. This saw was filthy green with algee and moss in cylinder.

So be the saw detective , columbo for saws. I showed what I wanted seen yesterday but one thing I did not show was the hole in air box. Put gas in tank over night to see if it leaks no leaks so worth effort to repair. Removed paint and beveled edges then cut screens front back. Applied cold weld. Happy with outcome. Slid carb on and need to ask question. Was this saw shelved because of the crazy port job or carb over tightened or sucked itself outback. Bad choice ultimately because of the corner when tightening.
