vole Posted April 4, 2008 Report Share Posted April 4, 2008 I posted about this last year too. My Briggs and Stratton 35 is playing up.Has done since I got it despite spending its value in repairs which dont last. I had very kind offers to look at it which due to pc problems I lost contact details. Its only 5 or so years old and only cuts a small garden. The spark plug needs cleaning continuously as it smokes very black.To start it I have to remove the air filter and pour fuel straight in.The primer bulb rarely works.It keeps cutting out every couple minutes,quicker if the grass is longer. I would gladly pay for someone to look at it because I have tried everything. I live near Macclesfield.I paid £70 for it serviced 3 years ago but it was still giving problems and would just buy a leccy one before paying that again. Many thanks Quote Link to comment Share on other sites More sharing options...
dustyfox Posted April 4, 2008 Report Share Posted April 4, 2008 well its losing power so I am guessing it is the petrol/oil mix and to much oil going in it. and if you are not using it often it could be that some bits a seizing up. Quote Link to comment Share on other sites More sharing options...
starlight32 Posted April 4, 2008 Report Share Posted April 4, 2008 I had one the same which started playing up, the Briggs and stratton 3.5 horse engine are not really powerful enough as they have a rev limiter so you cannot give them some more stick for longer grass which results in the engine idling. I ended up buying a Honda 4.5 horsepower 'Izzy' and that has been fine. Quote Link to comment Share on other sites More sharing options...
Axe Posted April 4, 2008 Report Share Posted April 4, 2008 I'm no mower expert but it sounds to me that the engine is running very rich. If you can, adjust the mixture screw and check that the choke flap is not stuck and does actually open. http://www.briggsandstratton.com/ Quote Link to comment Share on other sites More sharing options...
vole Posted April 4, 2008 Author Report Share Posted April 4, 2008 The plug is pretty oily round the threads when I take it out.Need to find the screw for changing the mix then. Thankyou. Quote Link to comment Share on other sites More sharing options...

Many thanks Hi Vole, I had a similar problem a year or so ago with same engine, problem was a £2 rubber diaphram, the mower shop told me what to do, as they had a month waiting list, it took me half an hour...... to find my socket set and 15 mins later the beast roared into life and one man went to mow as they say it fits somewhere under the air filter towards the carb and causes the engine to play up as you describe, for a couple of quid its worth a punt?? Hope you get it sorted as theres nothing worse than long grass, a nice dry day a a sulky mower D2D Quote Link to comment Share on other sites More sharing options...
