Stiga mower engine problem

[Kidds]

yeah got 2 walk behinds, they stick a fairly hard go on our mowing round.
mind you no seat as them ones make fer a lard ass
infatct could be rideons are for them with too much money or lazy or maybe both.....

and if your lawm=ns that big best put some ruminants on it and be more carbon neg. or ios it pos ? whatever......

I'd just as soon go over it with the flail tbh, as you say....too much money but still not enough for a Deere

robust engines onours anyway, deck rusted out on a previous one, but current ones are Galv. under paint.
Final drives are good as well. had a JD one once and they kept wearing out as thye were. metal to plastic.

fairly well designed and fairly built well stuff ir, .....sort of like the volvo of the mower world ....

My Stiga is playing up, reluctant to crank past compression with a fully charged battery, won’t fire with jump leads. Apparently the B&S are a bit sensitive to large valve gaps. Reset them (c/o YouTube). New fuel filter, battery and plug on Monday.

Ours did that a few months ago, valves behind silver plate on back of engine had partly come apart. Had help to reassemble and all good.

Had trouble with mine losing power , 1 spark generation wasn't working

Check leads etc.
Usually the starters either work or they don't.

If it's an ohv engine then they have a little decompressor built into the camshaft with a little spring that fails.
This causes hard cranking.

Are these Stiga any good then?
Looking to buy a new mower now I've made the lawn bigger and choosing between a Stiga and a Mountfield, just a different colour really as they are both the same thing.

Are you sure? Never used to be, but would not be surprised. Just googled, you are right!

Our stiga doesn’t appear to be wifey or drillman junior proof.

decent mower but often find it abandoned outside the workshop and grass half cut wen some rough arse has knocked the blades out of time!

Latest thing is headgasket between cylinder and an oil gallery has let go.

keep telling them to not cut steep slopes with it but they won’t listen! I reckon it’s been on a silly angle while running and that what blew the HG.

but they won’t listen and insist I’m wrong, One of these days I will probably find it upside down with someone under it.! They mite realise I’m right then!

I had very same problem as you, i found it in the end!!!! it was as simple as a rubber washer in the cap of the fuel tank was not letting air in. SERIOUSLY throw it away and you will be sorted

Changing mine to a Scag, same problems as above, runs fine one day another it smokes and backfires terrible, stiga decks are also made of chocolate, i have rags stuffed in holes to stop getting covered in grass.

I hate timed decks.
Terrible idea unless it's all perfectly smooth lawn with no dog toys hidden.

Single cyl ohv Briggs?

Is the head gasket actually failed or has it just bellowed smoke and oil from the exhaust?
They're bad for pulling oil through the breather on steep side slopes, it will clear though after 5 mins

The timed deck is appalling.

I'd go for a 3 blade non timed one next.

recreational mowing of lawns is a waste of resources,in the future it will be looked back on with disgust.

just do the bit by youre back and front door (to keep the rats away) and leave the rest for the bees and birds

Head is off and obvious where it’s blown

been drinking oil for a while now.

 

[PSQ]

The new battery, fuel filter and new plug did the trick, it now starts as it should (2008 Stiga Vila, 15.5 hp B&S).

we actually had one that was using a lot of oil but not burning it , on stripping off the sump i found it was simply the gasket that was slightly folded over /badly fitted in one place must've been poor assembly on it , simply straightened out and refitted with the same gasket was fine.

i did open up the governor a bit on that one as well come to think of it , just to give it a bit more 'swing'

we give them some hard work on sometimes unavoidably wet grass, i do admit.
