I have a Hayter Kestrel Lawnmower, with a Briggs and Stratton engine.
I was a bit of a 'barn find' when I picked her up and I couldn't get her running, so she sat in my barn for a few years.
Last year I finally booked her in with the local lawnmower services place and they've given her a good service and she's now running....sort of.
I've only run her for a short while using the fuel that the shop put in her. I know she's a 4 stroke engine and thus the petrol and oil are separate...I don't need to mix them, but I don't know if she can safely run on unleaded or do I need a fuel lead replacement supplement?
She'll be running out of fuel shortly I should think and I don't want to put the wrong stuff in. I've managed to get the manual for the mower, but it doesn't tell you anything about the engine and I'm struggling to find anything anywhere that does.
The other query I have is regarding oil and cooling. After a few minutes of cutting she comes to a sudden halt (engine not mobility). The only thing I can liken it to is an over-heating engine seizing. If you try to pull the chord it's tight, but if left for a few minutes to cool down she fires up and runs again. How is this engine cooled and could this be caused by the wrong oil?
Sorry for all the questions, but I'm struggling to find anywhere else to turn to.
