Chainsaw Repair

For what ever reason it's loosing it's fuel charge and I would suspect stiff innards in the carb diaphragms .

As just an observation this model is perhaps one of Stihls best efforts of any saw they ever built .I have two mags and one 038 av .The one souped up version which will cut on a par with an 066 but if it sits for a day requires up to 10 pulls to get started but after that fires 90 percent of the time on one .

I've been wrong a number of times but my casual observation is to re kit the carb .
