Webb mower help please

Hi all, a new user here and eager to learn, I have recently got into repairing mowers after mine fell poorly and needed a carb cleaning and set up.
I got the bug and for the past couple of months I've been working on small engines such as mowers strimmers and and hedge cutters.
The other day I saw a post on face ache for a webb mower for £14 and couldn't help myself and bought it.
I then found that it needed certain parts so I bought another for 50.
Anyway to cut a long story as short as possible, both mowers have different engines even though its the same mower.
So I've decided to work on one and use the other as a doner.
Both mowers are old 30+ year and they are the cylinder style.
Anyway today while working on the one I want to have as my main mower I found that when I was pulling the pull cord it was catching, after removing the grass protector I found that the cast metal behind is broken and the bearings had come out.
Please see photo attached.
My question to all is where can I sauce another one from, every Internet search I've done has come up empty, I've tried briggs and stratton and other dealers webs sites and I'm getting no where.
I won't let it defeat me but its driving me Nutts when I can't get this old girl back up and running.
Thanks to all for reading, I'm looking forward to reading your posts too.

Hi Frantic fox, and welcome to TGMF

You can find a Briggs and Stratton starter clutch at Garden Hire spares

Briggs & Stratton Starter Clutch Part Number - 399671

https://www.gardenhirespares.co.uk/1158-briggs-stratton-starter-clutch.html

You will need to unscrew that old part from your engine anticlockwise.

No problem.  Just bare in mind this isn't a genuine Briggs & Stratton part but a after market one, but it should be fine, and a tad cheaper than genuine.  ;) 

Note: You should also lightly coat the shaft with oil when you fit the new one otherwise it will start shrieking and could cause damage to the recoil starter spring.

Oil or grease on it Mike? I was going to lube it just wasn't sure on what one would have been best.
Loving the hobby it's fun and I'm learning as I'm going along.
I do need a pull cord and housing for the same mower, and an air filter and box.
Really thank you for helping.

I usually just use a drop of engine oil.  If you look at the end of the square shaft you'll see a small hole in the centre of it, you can get a quirt of oil from a oil can through that, inside that square shaft at the bottom of the hole there is actually a oil pad to hold and distribute the oil. 

Just don't over oil it or the ball bearings will start to stick to the sides of the clutch housing.  ;)

Hi mick, fantastic, it fit a dream once I worked out it was a screw on type not a pull, and I pulled it hard, luckily I didn't break the flywheel.
Anyway, I was wondering if you could point me in the direction of the carb and where the springs go.
The mower has a petrol tank carb so it sit in the petrol tank if you get me.
I have cleaned the carb but none of the springs linkages or throttle cable were attached when I got it, I have searched for a manual, or at least a diagram but not getting very far.
I've also bought the green paint to paint it once I've got it running.
I have given it a pull already and it feels like it would start as there is good compression. It turns out the engine isn't a brigs and stratton, it's a tecumseh, which I've never heard of, but that part did fit perfect.
Cheers

Mick

It's definitely a Briggs & Stratton if it's the picture you posted above, they are the only engines that use that starter clutch. Also Tecumseh never used the tank/carb combo, they had separate carb and tank.

I'm curious now, could you try and attach a photo of the engine please so I can confirm. Also one of the carb / tank assembly.

Hiya mick, The guy who I bought the mower off was the one who told me that the mower was that make, he fixes other cylinder mowers and said that he wasn't into webb mowers, I like the webbs and if I can get hold of another one for the right price and do it up I will be doing. lol.
I've attached a few pictures for you to look at, I have marked in yellow the couple of bits I was talking about in my early post.
cheers for replying to me, :D

Mick

Well it's definitely not a Tecumseh, it's a Briggs & Stratton.

The tank is from a donor engine judging by the colour, the throttle cable would normally go under the tank where you should see a cable clamp and control linkage. This is coupled to a governor spring and the other end of that spring hooks in the the governor arm at the bottom of your photo. 

It's a job to explain so I'll try and find a YT video or two so you can get an idea of what I'm talking about.  ;) .

Hi Mick, them videos are a great help, I had searched yt for days trying to find something like that to help but can never find the right one,
So after watching them both, it looks like I am missing a couple of parts for the carb, one been the long arm with the spring in it, and the linkage that goes on the carb for the long thing to sit in. which is frustrating. where would I get them bits from? I'm guessing in video 2 the name of my engine would be 130202? if that is the case would I just search that code and look for a carb that way.


thanks a million

Andy

Frantic fox

hi mick, I am thinking now that its called the throttle linkage arm, and bracket maybe? The code from the video brought up so diagrams but still a little unclear on what it is.

The other thing I noticed was where does the cable go to, as it doesn't show that in the video, is it a earth from the flywheel? and where would it need to go?

cheers Andy

Mick

If you mean the throttle cable, it should fit under the tank, the mounting bracket should have linkage for it. It looks like you have most of the parts from your pictures, though I can't see if the governor spring is missing.


A picture of the underside of the tank might help me to point you in the right direction.

The wire from the flywheel area is just a stop wire, this is normally mounted on one of the two breather screws.  The idea is, you short / ground this wire to kill the spark and stop the engine.  So basically you can fit a stop switch to the handles and connect to this terminal.

Hiya mick when I get home i will take a picture and post 8t on here for you to take a look.
If I can get the engine running I'm going to strip it down and re paint everything and make it look like it's former self, love these machines, they were made so well and sturdy, not like some of the rubbish on the market these days.

Thanks again

Andy

Hi mick,
Your right all the parts are there and the carb is now connected and all springs and governors are in their place like explained on them yt videos you sent.
Now I have another problem, there is no spark, I've tried cleaning the flywheel to see if it was the grease and dirt that had built up over the years, but after an hour of cleaning it down there still isn't a spark. Which is frustrating as I would have liked for her to have been purring by today.
I'm guessing that I'm going to have to replace the spark plug thingy that rests on the fly wheel, is that right or is there something else that I'm missing to get it fired up.
I still can't locate where to put the throttle cable, I do have two other same mowers but they have different style of engine, the second engine the throttle cable attaches to under the fuel tank like in the video, but this cable on the one I'm working on is way to short to reach, it looks like when it was attached it was on the carb as there is a washer and a screw to hold it in place, but where does the end go?
I have attached more pictures of the fly wheel and carb underneath.
Hope your enjoying your Sunday
