After a 3-4 very slow turn overs it fired into life with fresh fuel in. Not ran since last Sept while zorst was re-made. Well happy it just fired up. Although the turn over struggle is an ongoing thing? Battery is a Motobatt, & only 6 months old on trickle over winter. The starter has been disassembled & cleaned & looks ok. The earth lead looks good too. Any other ideas peeps?
