advise please
I have just picked up a second hand petrol mower.
It is a Red Devil one and quite cheap in construction. It works fine but I am worried about the fuel. The seller said it was just straight unleaded but I think it should have some 2 troke oil in. So the question is are lawnmower engines 4 stroke? or as I suspect will it be 2 stroke? Thanks for any advise. taz. |

Thanks for any advise. taz. There are both 4 stroke and 2 stroke mowers, and the fuel is not interchangeable without damage resulting. The easy way to tell the difference is if the engine has inlet & exhaust valves it is 4 stroke. If started and run for a few seconds the noise & tickover beat will tell you too. Most 2 strokes also say on the fuel tank or cap what the mix should be. Ask any mechanic - they'll tell you in seconds. Or phone the seller or Red Devil. |

Its a small world isn't it :-) The petrol cap has no mention of oil mix and the engine does run like a four stroke. I think I am being over cautious but my fear is of it seizing if I get it wrong. What specific should I look for regarding valve to confirm. Cheers taz. |
