XL Brush Cutter model differences?

[MI Old Saw]

In my quest for anything XL, I finally nabbed a reasonably priced XL BC in good shape.

It was not running, but I actually needed nothing at all except a quick cleaning of the carb. The diaphragm looked nearly new so I kept things as is. In the process though, I battled a Jerry rigged throttle set up. I noticed pretty quickly the IPLs show differences between early and late XLBC models, as well as XLBC-B versus XLBC-4.

Best I can tell, this is merely carburetor differences and differences Enza throttle cable assembly. Are there any other differentiators? I have no model tag on my unit, so I am still left scratching my head on whether I have a B or a 4.

But she runs good! Definitely a little more tedious carburetor install with the air vane governor setup. I’m going to find some brush to annihilate after I put a little time into the blade.

I could get it to pop before the carb cleaning, but now she winds out pretty good

I'm returning to this post, as I can't leave well enough alone, and my XLBC hunt continued on!


I'm pleased with the unit I have, but it's red, and I like blue...so I kept searching. Below is the unit I have currently. It runs really well, but I did manage to run across an earlier model blue unit, and that fits my collection better. This one happens to be an XLBC-A, with the more primitive early style housing and frame, and one-piece drum/driveshaft, and the owner was very open to the idea of making room in his shop by parting with it.  I had not realized either attributes were part of the initial XLBC design, and I am excited to add that to the collection of early XL's.  

A younger collector with whom I shipped by XL-15 bow saw to mentioned to me that he was also looking for an XLBC, and so I am passing the red one along for what I have in it.  Sounds like a win, win, win!

Now I would like to track down a XLBC-B in blue, and perhaps even a ST-400 (red only?).
