lads, my wedge shaped tasmin 350i mountfeid lawnmower has developed a problem.
I was hooning around the garden in my wedge, when it cut out.
Upon attempted restart, white thick smoke, and oil from the exhaust.
can anyone advise as to what has happened to my wedge, and wether i can fix it myself.

Mods, this is an engine 350i question and the guys on this forum know best how to advise.
Please do not move it, mistaking it for a homes and garden issue.
I find people on that forum are good for suitcase advice etc.

Possibly the rings have gone on the cylinder? You'll have to check it, err i mean all 8 cylinders by whipping the head(s) off!

Gavin,did you turn the beast upside down to erm check the chassis? If so youve probably mixed the oil up wrong side of all eight pissytons. Drain and replace with correct oil and clean or change all 8 plugs,may need to reset gap that sends charge to plugs,or go electric!

Do you also have a leaf blower? If you strap the blower to the input of your v8 wassisname you might gain a few (well a quarter of a) BHP

Sounds like you need to do a compression test first to see if there is a cylinder down before ripping the heads off...

Well now that depends. Regulations say you should have eight cylinders in an engine, but I can never remember. Did you have 8, or was it only 7? I guess the question you have to ask youself is... do I feel lucky?

Well do you, punk? biggrin

You will need:

Tools. The more tools the better, ideally in both Metric and Imperial designations. Contrary to popular belief, a Big Hammer does not fix all problems. If you only have an Imperial hammer, that may pose a problem when you meet a Metric widget.

Time. An abstract concept, so our lass believes I perceive it anyway. Five-minute jobs are always the longest, typically taking all weekend.

Patience. If you don't have it, you may end up at Patients.

An understanding/sympathising/tea-making wife/girlfriend/boyfriend/significant other/Filipino transvestite (think that covers it). Keep her sweet by promising at least, oh I dunno, 10 minutes of unbridled sex on the black leather sofa (the marks won't show, but the smell may take some getting out) after a bottle of Liebfraumilch.

Somewhere to work. Easy one this: wherever the car is parked, that's where you work on it biggrin

Perhaps some sort of manual/diagram/instructions for the engine. Sadly, the Big Dummmies series never did get round to the Rover V8, so you may have to resort to the bletherings of Messrs. Haynes, full of big words like camshaftsprocketpistonconrodinletvalverockershaftmanifoldgasketthingy. Look at the lovely pictures, see how the engine almost fixes itself?

A helpline number to ring in case of emergencies. Samaritans is always a useful one to remember. Failing that, I hear Busty Housewife, 42, offers a cut-price rate before 5PM.

Specialist websites. Ah now you're talking. DropinaLS6.com is a good one, as are BlowMyRover.co.uk and Polishmyturd.com. Avoid websites full of wordy ramblings and pictures nicked from other people's work. whistle

Some mates. You know, those mates. The ones who will offer loads of advice on unrelated issues, tell you stories of how they once had a slightly-similar problem but with a completely different car and how it turned out to be the petrol station's fault for getting the hoses mixed up.

Crack on: it'll be a five-minute job for a man of your abilities biggrin

Gav, it would be helpful to know what model Mountfield it is.

This will tell us what engine you have:

  • Mountfield's own 100cc 4 stroke OHV (this is the latest performance spec)
  • Classic 35 Briggs & Stratton 4 stroke
  • An old Brigs & Statton two stroke
  • North Coventry Kawasaki (Very rare & identifiable by the stage 4 ported head);)
As you explained it to me, you ploughed into some heavy grass, which stalled it.

You then said you dug out the wet grass that was clogging the blades.

Did you by any chance turn it upside down to do this?

If so the oil from the crankcase could easily have found it's way into the combustion chamber.

If the exhaust valve was open this oil will fill the exhaust system so when you come to re-start it will smoke like mad.

Leave the mower upright overnight, put a new plug in it, and try again.

Chances are the smoke will clear and you will be back in business.

Had a problem with my V8 Mountfield a while ago
which when I took it to "a man who knows" said
I must have leant it on one side and the oil had
soaked into the air filter so it wouldn't restart.

Check the air filter before trying to start again

HTH

Cheers

Dave, its a Rover V8 mountfield (shhh)

Have had my "car" the right way up since, and it started first time.
smoked for a while, then back to normal.

You are right, i turned my car upside down to clear a blockage, and the oil must have seeped (barsteward)

Thanks for all yor help with my "wedge" lads....and thanks mods for turning a blind eye to my predicament.
