Honda GCV 520 engine mixture adjustment
Hello,
Its been many years since I was here so I don't think anyone will know me - but if you do, Hi! I'm also conscious that this may not be the place to get an answer on a lawnmower engine, but I'll try... My lawnmower has a Honda GCV 520 engine fitted and I find it is running too rich and 'hunting'. Nowhere can I find how to adjust the mixture, everything says 'refer to dealer' which I'm reluctant to do! - any pointers where to look would be greatly appreciated. Air filter is new this season and clean and no air intakes are blocked. Thanks all, -- David |

Air filter is new this season and clean and no air intakes are blocked. I used to own a machine with a similar Honda engine and STR there is no mixture adjustment. Have you cleaned the spark arrester? if that's badly clogged it can cause bad running. Badly adjusted valve clearances can cause bad running as well. If you don't have a maintenance manual take a look at this link. https://www.honda-engines.com/Engine...X37Z5Z6110.pdf Mike |
