I may have scored a Super 1130G from someone out of state. Have a friend in that area headed that way now. From the pictures the seller posted I'm seeing what looks like a crack in the corner of the drive case. Not sure it's a big problem regardless but I asked him about it while negotiating price and he went to look and said it's not a crack that it's a plastic spacer... I'm pretty sure it's not but have never had one of these in front of me before.
Anybody?

I'm not unwilling to attempt a weld but I'm wondering how far it goes on the other end and how much it really matters where it is. I don't get the impression it's a terrible thing but again, I don't know this particular saw very well. I am however looking forward to getting to know her!

Well *&%**$#@$#@@!!!!! Doesn't matter anymore. My friend got there, met the guy at a local truckstop and put me on Facetime on the phone so I could see everything. He took off the air filter cover & filter and there's a Walbro SDC carb under there with a long black tube off the end. I said "that's not the right carb for that saw at all" and the guy says that's what's always been on there since he's had it 25 years. He tossed the saw back in his car & high tailed it outa there without a word! Was trying to think on the run, if he'd come down in price enough, I'll get the right carb but then I'm thinking god knows what else is cobbled together. Maybe the piston & cylinder burned up from the SDC running it lean.. Oh well.

Later 1130G’s and S1050’s came with a Walbro SDC60 carburetor, and yes it does have the long black tube. They are a fixed high jet, with only a low mix and idle speed screws. That 1130G was one of the very last ones built. |

Just for reference, here’s a pic of one of my 1130G’s with the Walbro carburetor. Homelite started using these in the late 70’s. The easiest way to tell without removing air filter is to look where the hi/lo mix screws are. With a Walbro, they are plugged with chrome caps.  |

Thanks Greg. That's exactly what it was on there. I guess the tube is used to increase the velocity or the airflow?
Still can't get my head around it, the same carb that's on our 58cc Super XL's on a 100cc saw. Almost like taking the HDC off my Super 2 and putting it on my Super XL.. Was it a different version SDC, with the jets opened up more or something?

Was it a different version SDC, with the jets opened up more or something? It is NOT the same carb. Walbro SDC is a series of carbs, the operating principle is the same, but made for many different types the engines from small to large displacements. Jet sizes and venturi size are very different. For instance, the SDC62 for a SXL has a venturi size of 14.27mm. The SDC60 for a 1130G/S1050 has a venturi size of 19.84mm. Even though all SDC's take the same repair kit, internally, they are very different from the SXL carb to the 1130G/S1050 carb. Hope this makes sense to you. |

I always thought that the series numbers was just the "trim package" essentially depending on which model saw it might be going on. Surprised to hear the venturi size would be different. That would mean different castings all together or did they machine one open more from a base size casting?
Still seems like such an odd thing to have done, going from a Tillotson HL carb to the Walbro SDC on that saw. Have to wonder what was behind that decision.

Great timing, I just last night brought home a 1130G and a Super 1050 Auto. A local gentleman asked if I wanted to take a look at a couple of old Homelite saws that occupied the corner of his shed. The 1130G is the older of the two, equipped with the tillotson and the 1050 with the SDC Walbro. Thanks undee for sharing the information. The 1050 has spark, but needs a few new parts. The 1130G is in great shape/complete, but need to check out the fuel/spark. Looking forward to seeing the two of them run and cut.

Greg your encyclopedic volume of knowledge on these things continues to impress. Thanks for the info, at least I'm a little better of next time, if there ever is a next time.
I still find it difficult to believe the claim of "improved carburetion" but who knows. Would be interesting to see them in a head to head test and find out if it was just Walbro's marketing claim or not.

You do have me wondering about what you paid and if it was in line or not with what I had going?
There were a few things that played into my issue where I just wasn't in a trusting mood even before the carb boondoggle. He had said he had a few lookers but no offers. Always makes me wonder why. The bar obviously had a grinder/sander taken to it, not in the most skillful manner. I also notice in the one picture the bucking spikes were mounted, what I would call, upside down. Not sure if there was a reason for it that I'm just not privy to, never having been a logger, but it raised an eyebrow.
Hopefully if somebody does pick it up, they report back one way or the other.

Haven't yet tackled the Flicker thing, going to give it a try. Very pleased with finding these two saws, it's time I venture into the picture arena. I do better with a saw in my hand than a iPad.

One of my 1050's has the Tilly carb and the other two have the SDC. Since the saw I was using to mill with had the black tube, I was thinking about taking it off, and putting an elbow in place, pointing up. Was going to make a custom over sized, super fine, air cleaner to keep the fine dust out. Of course I would have to run it with out the air box cover. Then I got to thinking it might mess up the air flow and settings, so I just bought a Stihl 660 to mill with. No sense in dogging the saws I really love.
