Found a Stihl 024 on a country tip. It has plenty of compression and after replacing the plug and giving it a dose of fuel via the plug hole, away she went. After that starts first pull every time whilst it is warm but after being left for a while will not start from cold without the fuel dose down the plug hole!!!!!
Reluctant to tackle the carby and puzzled by screw adjusters on the side which are marked "H" "L" and "LA". Any advice would be welcome.
