I have a new coil. It works. I used spark tester and light comes on but no spark. I used same tester on other engine and get light and spark. Why no spark on first example. Flywheel is clean and the coil is installed properly. Any ideas? Thanks Paul
Mower starts cold perfectly. Runs fine. When I shut it off to empty bag it is almost impossible to start. New magneto and plug. Cleaned carb and will put rebuild kit in. Any suggestions. Its well maintained. Possible valve issue? Head bolts are tight. Please help.
