Thanks for the advice, but it appears that you can’t post onto their forums before you are a member.

I thought this forum covered lawnmowers or have I misread?

Yes I believe it is pretty original. I bought it over ten years ago, and ran it for a few years just dragging stuff, firewood and the like, around my place, which is on a fair slope. And I look forward to using it again for just that.
The track got stuck a few years back and I’ve just been too busy to deal with it, but have recently got my enthusiasm back… but have yet to try the engine again. Reckon it’ll still be OK though.
There’s a fair bit of gear with it as well, I’ll drag it out of the brambles and post a photo one of these days.
Thanks for your interest!

The engine model,type and code numbers should be stamped at the front of the cowl (just above the spark plug).If its had a new cowl fitted in the past then there will be NO numbers stamped on it at all.
The 11hp B&S engine is i think a 25cui (25 cubic inch capacity) engine so your model number stamped on the cowl should start with 25####
The earlier models also had a down swept exhaust system (which runs down the LH side of the chassis) very much like a car uses.

Good day Steve
You may do better with assistance with the old lawnmower club as that’s what they are about.

Still haven’t found the engine number on the side of the cowling, it might be hidden by the petrol tank that raps itself around one side of the engine or hidden by the air filter on the opposite side. Engine is as shown in the early 1980’s parts lists and diagrams.

I have tried to establish a specific year from the parts list/diagrams by looking for simple changes in design like how the dash board lights are mounted. Change from shaped petrol tank engine mounted to square bulk head tank mounted by the side of the battery, but I guess the Westwoods design developed continually between years and I won’t be able to pin point a year until I find that all important number and as mentioned replacement parts or mods could have been installed. All of your suggestions and links have been very helpful.
Thank you all for your help.
Eric.

You might find this link interesting. I hope it works.

It will be mid 1980,s.Providing its still the original engine fitted (or cooling cowl fitted) then its easy to date the engine as the reply above.

Where the spring is fitted in the second photo it’s a larger hole so when the rotavator was repaired they must have thought the throttle cable had to go in the largest hole.

[vhgmcbuddy]

The second picture is correct.

Hi Jerry
Your MG40N looks good very original. Neil Jarrett is definitely the man for spare bearings and hub seals etc. Does the engine run? I recently bought a similar machine from South of France, a good degrease /pressure was followed by a spray over with WD40 makes a huge difference to the appearance. Will you be using the machine or just for show?

[vhgmcbuddy]

Hi Dave
I’m happy that you have put it on your register. For info. the engine no. is 3699184.
Thanks for your offer of help, as I said my priority at the moment is finding sources of spares before I start.

Hi Guys,

Thanks for the tips. I’ve been in touch with Neil and he is able to supply me with a diaphragm, which is good news. 🙂
That hopefully will allow the delivery of fuel to the carb. It is strange that there is no evidence of a TVO tank. So yes, I assume it will run OK on petrol..

Does anyone have any advice on things I should check with regards to the magneto? It does seem to spark, but perhaps not every time when turning over.

Cheers

James

Hi James Neil is your man for a diaphragm.
The only issue with the TVO manifold may be that straight petrol will vaporise in the manifold before it reaches the cylinder which may cause poor running when hot. On the basis that the side valve engine is pretty inefficient and the tractor has obviously run since the change I would expect that you will have no problems using low grade petrol.

Thanks again Charlie.

The project continues…

Rebuilt engine fitted.
All oil drained and refilled.
Grease nipples filled and tyres pumped up.
Cutter bar fitted and blades adjusted as well as possible.

It started first pull and cut tall grass well without quite shaking itself apart!

Sadly a quickly deflaing tyre stopped play.

So to the next phase…

2 tyres and tubes on order.

Anyone any idea where to obtain a set of the curved brackets that press down onto and retain the blade. Mine are worn to the point of almost being useless?
