Is there a way to measure the coil output with an OHM meter? I'm down to my wits end, Homelite weed eater, rebuilt carb, replaced fuel tank last year, ran great for about 4 months. What it's doing now is it's hard to start, runs at idle only with choke on, give a little gas and dies. Been through the carb and fuel lines thinking it's starving but it appears OK. New fuel lines and filter included with tank. The spark looks weak to me. Being a Homelite, is it time to upgrade?
