a little more detail on the husqv 55 rancher saw problem.
the saw was working fine consistently for years till this last quit. the blade was dulling and the bar chain was hot although i believe was still oiling when the saw just died off as if out of gas. refueled and reoiled and tried to restart. never started again. no tough pulling or siezing. changed the plug, cleaned the air filter, and took off muffler. magnito gap was at business card span. tried to start with a little gas mixture both in the carb directly, and very little in the plug chamber. no coughing or start attempt noise . just normal pull start with no firing. what happened from one minute to the next? i have not tried the carb screws or adjustments yet but will try on the weekend. one more thing, the chamber is definitely getting good spark as i verified that both with the old and new plug outside the chamber i appreciate all your comments and help.
