In rebuilding my 85hp Johnstone 2 stroke I needed to build some specialised tools for the Link and Sync they include;
1/ A four plug air gap spark tester
2/ piston stop tool
Both took less than an hour to make, cost virtually nothing and work a treat
I have enclosed some photos to help with the building.
