I got given this sad looking mower this morning.....
Step 1, water blast to see what's under all the gunk.....
It's got compression, I will clean carb up, and see what happens.

I have 3 complete Tecumseh Victas in various states.
I'm hoping to get at least one going out of the three.


Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!

Hi Speedy,
It's obviously missing the air filter assembly, but also the throttle control plate and the governor spring.

Good wheels on the junker.
Upon close inspection, I see that it is the cheapest grade base where it doesn't even have the metal divider under the front to form a round cutting chamber. The Lawnkeepers by Victa are all like this. That's why I take some off old rusted out bases to put onto these.

I took the carb apart, cleaned it and put a new o-ring on the emulsion tube.
I attached the throttle control plate which was laying on the deck......
Took cowl off the clean flywheel area and clean rust off coil ends and flywheel faces. and blow dirt out of starter cup.
Found some data on ODK posts on Tecumseh ,which are excellant..... Watched a few youtube videos on cleaning Tecumseh carbs etc.
It started forth pull, and ran at half revs.. I let it warmup and run for a while and mowed some of front lawn or grass seed stalks.....
I've just gotta read up on throttle problem, but it's a good problem to give brain a challenge. As we get older , we have to never stop learning..............
cheers

Nice progress you're making speedy and I for one will benefit from this as I have three dead Tecumseh Victas waiting for attention but just not inclined to play with these unkowns even though they're a nice motor when they're going. I get frustrated easily and that's probably been the biggest dread factor.

Your topic here will help.

OK I screwed in the idle screw, now I have 3/4 revs, which mows the lawn pretty well, but the throttle doesn't make and difference. It's like a new Aldi mower ,one setting fits all.
Maybe the chondas increase power under load, maybe they just die....
It would make a nice present for a lady friend.....

Can someone refresh my memory on where the emulsion tube is in the carburettor and what it does?

Tiny tube with many small holes above the main jet. Honda has a brass one that gets clogged up quicksmart - basically allows better mixing of the fuel and air without needing really rich mixtures.

Technically, tecumesh has a pretty basic plastic one, but anyway...

So that one clogs up faster than the speed of light then?

In a chonda with crap fuel yep haha

In fairness, what I have normally found is the main jet clogs after the smallest holes in the emulsion tube. So what happens first is you get rough running, surging, stuttering. Then if you leave it longer the jet clogs.

Now most people will clear the main jet alright, but forget about the emulsion tube. So they will usually get it back working - will run rough because it can't blend the fuel with the air as efficiently.

I reckon of the 50+ people I have helped with Chonda carbs who sort of knew what they were doing only 10 had the emulsion tube out or knew about it.

By the way - don't try to get one out of a Quantum - they are fixed in. I don't know if you can even call them emulsion tubes on quantums as the fuel doesn't really disperse until it hits the throttle butterfly - very cheap

I made an emulsion tube from a ball point pen tube....
The mower ran, and I mowed my front lawn.
But for more revs I had to jam half a wine cork between govner arm and frame.
Just a bit of R&D. It leaks oil from valve cover...... so I'll keep it for my lawn.
I couldn't give it away as it would be hard explaining how to keep it running.....
One mower centre here said I couldn't get parts for old Tecumsehs.......
Mum always said I was a bit rough.

That's food for thought speedy. Makes me wonder if I'll get one going out of my three.

Rislone stop leak (silver bottle with blue bit) works really well for sealing leaks you can't be bothered fixing.

Can get it about $8 on special and get about 4 mowers out of each bottle. But give it a really good run and flush as you have to use it every oil change for it to work. You want a clean sump so the oil doesn't go dirty straight away


What are you using for an air filter?

No air filter , but I have the manifold. I'll just use foam. I'll make a lid for air box.

Give it a go MF
