Lawn mower will not start

PSE Composites Limited - The next level Rifle Stocks
When I got my first Izzy however many years ago, a lawnmower mechanic mate said to put a new plug in every year to keep it happy… of course I only do that when it becomes difficult to start! 🤣
Worked with next door’s cheap n cheerful Screwfix special too

Cheers

I might be saying something stupid...... but. I have no knowledge of that particular honda 4 stroke (take it is a GV100?) But the bigger honda 4 strokes have caught me out with the oil sump/reservoir, they have a little electrical sensor in them, and if the oil is very dirty or too low the engine will not start.

Just a thought

Only a small old domestic lawn mower, no fancy electrics. Lawn mower model is HR173. Turned out it was the spark plug.
 
Not got inclination or time to read whole thread but if it’s not been suggested…. No matter what machine it is …start every season with a fresh plug and before “ laying up “ drain all the juice.

Don't think anyone's mentioned the spark plug. Clean it, or maybe get a new one and check the gap is correct.

Yes, mine was sooted up after a summers use. Needed a good clean and was back up and running. Also dont use the cheapo petrol it will ruin the engine

Well it’s that time of year again

Lawn mower out of the shed and the damn thing will not start

An old Honda HR173, from what I’ve read they are pretty much bullet proof. Pull start petrol.

Third or forth pull and it fires, runs for five or six seconds then stops. Will not fire up again until it has had a long rest.

Straight to YouTube, I find a tutorial for this very model. Go out and buy a spray can of carburettor cleaner. Strip down and flush out carb and its components as instructed on the video

Empty old petrol from the tank and half fill again with fresh.

Reassemble.

Bloody thing does exactly the same, except fires up second or third pull this time but then again fades away after a few seconds.

Anybody able to offer any advice before it goes to the tip?

Valve clearances mate. They’ve tightened up. Gets hot, valves expand & lose compression. Cool down, contract restarts. Put money on it
 
I’ve an old Atco out back to restore ( same as Sid James’ one in bless this house)

But I cut the grass with a battery Stihl. Fantastic thing, best thing since sliced breed
