Just an update, I started it and it kicked out some white smoke as you said but sorted itself out after a few seconds. I've used the machine twice since and it runs perfect, so all the worry over nothing lol. But I won't be tipping it on that side again, I agree the manual is probably printed wrong or something. Thanks again 👍

Thanks so much for your reply Mick. I thought I had messed it up and was dreading having to fight with the manufacturer. I'll post some pics up tomorrow. It's a 173cc 4 stroke if that helps.

You've eased my mind for sure. Thanks loads 👍

Hi all, I'm just after a bit of advice please.

I bought a brand new ParkerBrand 21" petrol lawnmower.

I'm brand new to petrol ones, so I followed the advice in the booklet to the letter. After setting it up and a successful run on the front lawn, it's recommended to clean it thoroughly. The manual states: "tilt the lawn mower onto its left side (opposite the oil filler neck)" to clean the underside.

So I did just that, and the oil poured out of the air filter and into the floor.

I googled it and have now found out there is a golden rule - apparently never tilt a lawnmower into its side.

Anyway, I haven't tried starting it. I've cleaned the air filter out and mopped up as much oil as I could see.

What should I do now? Should I empty the fuel, empty the oil, pull and clean the spark plug, flush the system through with something?

Thanks for any advice.
