Giday I'm after a head casket and the model number from what I can make out is 110908 the second digit was hard to make out . The type 0440-1 and the code 79030204 which is marked a 187 cc. ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-6680-11510-img_20130707_115951.jpg) And piston rings if possible . I've looked at engine parts on outdoor king but I'm not sure what to order because of the model no.

Hi roebuck. That model number is valid, and is a 187 cc engine. If that second digit were wrong, the engine size would not be 187 cc. The engine was made on 2 March 1979. This is the Illustrated Parts List: http://bsintek.basco.com/BriggsDocumentDisplay/Z6lnsHVJ1DajI.pdfThis is the Operator's Manual: http://bsintek.basco.com/BriggsDocumentDisplay/msowGK-K_ny7tH217FzoPu.pdfThe part numbers are given in that IPL. If you have any problems finding them, let me know. The IPL only shows a Gasket Set, not a Head Gasket - the Head Gasket Item No. has been blanked out. The rings are Item 26, standard bore is P/N 391654. If you send a message to Bruce, and tell him you need those parts for a Briggs 110908, he'll find out if a head gasket is available separately. From my search I think it is P/N 27171 for a Briggs 110700 series. A whole multitude of US sellers on ebay have them.

Thanks Grumpy, I've always had trouble trying to order parts from the net due to parts numbers from engine numbers. On a funny note my daughter came out to the shed to see what I was up to. I said I had to wash the mover so I can work on it, my daughter then said That looks like an old mower and I said the mower so old that in the old days you had to lift it onto the front wheels to mow the yard. She then replied STUFF THAT!!!! The boss and I could not stop laughing. ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-6680-11514-img_20130707_120017.jpg) I have more on this mower so I will post photos as I go . I want to weld the fuel tank as it has a large chunk of metal (alloy I think) out of the tank right where the tank bolts on so as I get the photos you'll be able to see what I mean, thanks roebuck.

Let's see a picture of the tank, so we can understand what is wrong with it. Welding the aluminium tank is impracticable, not only because aluminium welding is difficult and expensive, but also because the tank is made in 2 halves, attached to each other with a mastic seal in between. If the tank is heated that seal will melt, run out, and leave you with a useless leaky tank.
If the tank is damaged you will need to get a second-hand one to replace it. That should not be difficult. However at the moment I don't understand what could be wrong with it, unless it had received some unusually savage treatment at some point.

OK, the tank mounting point has been broken out of the aluminium casting that forms the top of the tank. Looks as if someone has tightened the retaining bolt with the tank and carburetor assembly not properly in position. I see no reason why the substitute tank should not work except for the replacement tank lacking the feature circled in yellow: ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-2772-11529-briggs_fuel_tank_comparison.jpg) At the moment I don't know what that feature is for.

That's the broken bit off the tank , I should have put it to the side . ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-6680-11531-img_20130710_101042.jpg)

It should all be good then roebuck. And that clears up the mystery - I thought I remembered that tank well enough to know if it had a lump there. Does your carburetor have an automatic choke? It looks to me as if it does. If so you have to preload the diaphragm when you reattach the carburetor to the tank, with the diaphragm in between. First though, check that the top of the tank is flat, by laying a reliable straight-edge across it diagonally. You can see the instructions here: ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-2772-11534-bs_auto_choke_1.png) ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-2772-11535-bs_auto_choke_2.png) ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-2772-11536-bs_auto_choke_3.png) Please report back here as you go.

Wow Grumpy ther is a lot more involved with getting it right. I will follow the information you've given and get back to you . Oh and it is a automatic choke. ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-6680-11538-img_20130710_101131.jpg)

Yes, the repairers hated the auto choke because you needed to read the instructions first. The first time you do it, you have to pay attention to the manual, but you'll soon get the hang of it, and after that it's easy.

Right click on the image you want to draw a circle on, select copy. Open paint program, select the dotted square icon at the top. Right click in the white area, then select paste. Now you can use circles, ect from the tabs at the top of the page. Now you can save your ammended image as a JPEG file.

Thanks Mark, I will work it out but I have to download an app first according to my daughter because I don't have paint photo on my tablet. I have received the head gaskets allready from outdoor king ,crikey that was fast.I've put the mower together and it runs really good . With the imformation Grumpy gave me I got the b&s to run smoothly ,got a nice idle and even all the way up to high speed it took a little bit of playing around but now its sweet , I do have a small oil leak from the valve cover and I will replace as soon as I can. I then went and tunned another of the simular engine using the same information and it's running better than ever . Thanks heaps Grumpy great stuff. Roey

I'm not fond of your spark plug lead, and the governor linkage seems to be missing in the pictures. Can you post a picture of the assembled engine? I'm glad it's now running well, but the best way to keep it doing that is to make it as similar as possible to the way it was when it left the Briggs factory. I understand you don't want to spend money on an old non-collectible engine, but I'm sure you do want reliability.
The genuine Briggs spark plug lead is very reliable - I once clamped one between the air cowl and the governor plate so hard that after a couple of mows it shorted the ignition to ground, but as soon as I put the wire back where it belonged, it was as good as new.

Hi Grumpy , the spark plug lead has a join in it and it peviously had a join in it with normal electrical wire so I took the wire off it and with proper coil lead added it and for a bit more length. Best I could do with what I had but I would of liked to of put a whole new lead but it looks as if it is glued or moulded into the coil. When I come across a spare coil and lead I will change it over. There is a spring in the picture but hard to see so I'm not sure what you mean by the govenor linkage so tomorrow I will take some more pictures and post them . The original carby and tank had an extra hole in it for a screw to go in it and if you look at the last photo of the two tanks carefully you'll see it . The screw n the original carby and tank ran through the carby about 5 mm away from the airfilter screw heading towards the intake. The new tank didn't have this hole in it to screw ito it so I drilled one and it seems to of worked fine. The motor is running fine from a nice low idle and as I throttle up it runs nice and even all the way to the top and back again . I'll take a photo with the air cleaner off tomorrow and along with the govenor setup aswell . Thanks roebuck.

Thanks for that roebuck, when we see the extra pictures it will probably all become clear.

Ok here goes, ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-6680-11572-img_20130714_094901.jpg) ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-6680-11574-img_20130714_093320.jpg) ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2013/07/full-6680-11575-img_20130714_093301.jpg) Little bit of paint on it will look ok.

Are you using that piece of wire to hold the auto choke open roebuck? Of course it should always be closed when the engine is not running, if it is working properly. It also provides acceleration enrichment even when the engine is warm, which is one of the reasons why the auto choke models are nicer to use than the manual choke versions. It does not interfere with hot restarts, of course, it just sucks open as soon as you pull the starter.

Yes Grumpy, the wire is just to hold it open so as I could get as clear a photo as I could to show you the extra screw inside the carby . Thanks again roebuck.
