Hs45 Want Crank Or Run
i have a 2 year old HS 45 hedge trimmer. All it's had in it is the pre mixed gas in a can with no alcohol. It want crank or run. When it does crank it bogs down. Has a new spark plug new air filter and I purchased a 6 pack of oil when I bought it to get extended warranty even though I don't use it. I have tried crimping the gas lines to make sure it's not flooded. It still does the same. I have tried the adjustment screws on carburetor and still no luck. I have 2 trimmers an old farm boss and a mini boss chain saw and they all are trouble free. I have purchased a blower and this trimmer in the past 2 years and the quality of stihl has gone down. Had nothing but down time with them. Tired of taking them to the shop when I wanna use them. Can you point me in the direction to adjust this trimmer. I work on electric and engine driven pumps and generators for a living but this trimmers got me stumped. Thanks
