Mountfield R28M Ride-on-Mower Mistake? Any tips..?

sujsuj

I have been using my Mountfield R28M for last 2 years, slightly rough use due to the area that need to cover and me being new to this type of machines.
This weekend I tried to remove cutting blade for sharpening which I couldn't remove. So I ended up tilting mower to one side to sharpen the blade.
Stupid decision I regret it now..After this tilting exercise looks like engine oil leaker allover now Mower is not starting!! ...Any suggestions..?

I tried to fully charge battery thinking its a battery issue, that didn't resolve the issue.
I opened the  cover and did a full inspection to dried as much leaked oil I could.
when I start the engine I can hear kicking sound but engine is not firing with continuous noise. Thanks 

Any help much appreciated.

Obviously check the oil level is correct before restarting.

Most likely some oil has found it's way into the combustion chamber and has oiled the plug, preventing a spark. Remove the plug and check it - is it glistening? (Petrol glisten will smell, oil not so much) Wipe it as clean as possible, and either blow-torch it dry (and brush away the carbon formed) or wash it in petrol and let it fully dry.

Spin the engine with the plug out to dispel any excess oil, and refit. If you use the blowtorch method, replace the plug when hot, and try a quick start.

I'd give the same advice as last year when a similar thing happened....

Lawnmower engines are typically designed so the oil stays where it should be when the lawnmower is within a certain amount of tilt from being 'flat' on the ground.

Tilting a petrol mower on its side to carry out maintenance is a sure way to end up with a bigger maintenance job.

The usual remedy is to leave it to allow the oil to flow back to where it should be, but if you've attempted to start it in that condition you could have caused permanent damage to the crankshaft, con rod or piston, or have an oil-soaked spark plug, or have oil in the carburetor etc.

where is the plug located..?

Please see above video, if any help based on that sound will be great. thanks

Yes didn't learn lesson first time...this is whats happens now

Ok, that sounds like hydraulic lock as S62 suggested could happen. In essence, the combustion cylinder has so much oil in it that the piston cannot move. If so, it's fortunate that the starter motor isn't powerful enough to 'force' it around, which could cause major damage.

That's guesswork, tho'.

Ok, I'd assumed you had some general knowledge of petrol engines... I'd also assumed, from your description, that the engine was actually turning or spinning, but just wouldn't fire up. But it doesn't even turn or 'crank'? Lawdie.

When I mentioned 'plug', I was referring to the 'spark plug', which is the component which needs  to spark in order to ignite the petrol/air in the cylinder, and get the motor running. By removing it - for which you'll likely need a spark plug socket - you will both release the 'lock' pressure in the cylinder - which should now allow it to spin freely - and also allow it to be cleaned so that it can spark again.

So, first step is to ID the spark plug, pull off the lead on the top, and remove the plug. All this will be covered by vids on t'net. What info do you have for your specific engine? Check that out too.

If you take photos of all 4 sides of that engine and post them on here, one will likely have the plug in it.

Your biggest mistake was buying that model in the first place. How do I know? I have the hydrostatic version, shortly to go on eBay. It's a big pile of junk, touted as a 'British brand,' but not made here. I gave up on mine and bought a Countax second-hand, which does what I ask, rain or shine. Mind you, it would be quite a task tilting that over to sharpen the blades! It's a job I give my local garage guy, who's quite a whizz with ride-ons, but the Mountfield belt replacement was so well-designed, he was almost defeated by it.

A pity. It's a handy little machine, if it actually picked-up damp grass and had good access to the working parts. As it is, neat Italian packaging and the usual promise of their 'interesting' engineering ideas.
