I do not know what is going on but I am having problems with tanaka trimmers and blowers. I had some 270pf that were gutless so the dealer being a stand up guy traded them out for 280pf! Much better power but I have had them for a week and they will not start if they have been sitting in the sun light for an hour or so. Today the clutch housing on one of the 280's melted. Now I also bought two 2510 blowers that take 20min to get to run when they sit in the sunlight. What is the deal!
