Ever since I have looked at my buddies 22000 series and researched on it to get repairs done, I’ve decided to keep and eye and ear out for an older model.
Well happy Birthday to me! Today picked up this 10000 series 7hp she runs good has a few issues like no spark plug boot, missing a few screws, but runs pretty good for being 49-50 years old, actually is in better shape than I am!! 😊 Will do the usual oil changes, plug, new belt grease. But no more shoveling is a prayer answered. I read probably 400 threads and pages on this site about each series model and I think I got a good deal for a buck and a half. I’m sure I’ll have questions once I tinker with it, but starting 2021 with no more shovel is best birthday a guy could want!

Great score!
Looks complete and in great condition for it's age. With a little maintenance and lovin' she should give you many years of back saving service.

I missed our big December snow of (10”), I know some of you are like 10” is a dusting but to us Steeler fans 10” (of snow) is a big event! I do believe that we will get enough in January then again in March (unfortunately) as by then I’m ready to bust out the motorcycle. Yes I will probably do the whole block!!

So, I was checking the Tecumseh manual, as I wanted to get the correct carb rebuild parts. It is the series 1. But the bowl has what looks to be a drain valve or something and that is not shown as replaceable part, but it leaks ever so slightly, yes I did turn gas off. If anyone has something and has rebuilt their’s I’d appreciate help in ordering.

those are pretty common on a lot of older machines. a lot of the time people usually seal up that hole with gas resistant sealant or replace the float bowl with one that doesn't have the drain. i believe if you wanted you could fix it. there is video's on youtube but personally i feel like it would be better off without it. 1 less possibility of a leak.

Ok that makes sense, I’ll try to find a replacement bowl if not for sure will get sealed looks to be aluminum and I could remove it and weld a plug.

you can usually find them on older lawn mowers if you are looking to try finding one for free. there is a lot of Tecumseh lawn mower engines out there still and they don't usually have a drain. people put them out for scrap or take them to the dump all the time.

Ok, decided to dig into it a little since no snow forecasted for two weeks. This is what the cylinder, valves and head looked like when I popped it open. This piston aside from carbon buildup appears to be in good shape. I did see some scuff marks on the wall of cylinder valve side. I’ll attach pics I know pics are loved. I will get that all cleaned up before she gets back together. I think I will pull the cylinder off this spring and check the rod bearings. I have a feeling the routine oil changes were not made on this poor thing. She does run great . I should of checked compression before I busted her loose but oh well. If anyone has suggestions I’m all ears! Btw I use a brass wire brush to clean it all up. This was a two beer job.

Nice job and good for you to use a brass brush for the clean-up. Interesting to see those scratches on the cylinder wall....I wonder what caused them? Could apiece of carbon be hard enough to scratch that surface?

I don’t think it’s carbon. When I cleaned the head, there was scrape marks on it as if someone scraped it clean so I’m not sure someone else was in here. I also cleaned a few casting blemishes up with my dremel between where it slopes towards the plug it was pretty rough there but now smooth transition. There is some pitting but I don’t believe that will hurt. I think I will check the valves clearance and lap them since I’m this far.

those definitely seem like odd scratches in the cylinder. can you feel them if you try running a finger nail over them? otherwise it does look very clean in there like someone was in there already cleaning things up. would definitely expect to see a bit more carbon in there if no one has done any cleaning in the past.

Good question! I cannot feel anything but have zero fingernails- haaaahaa. I drained the oil today it was nasty dirty black and some grit non metallic was at the bottom not sure what that was but Definely hasn’t been changed in a long time, it also stunk almost like gear oil. Weird.
