today was over 100 degrees and i was out mowing and whenever i had to bump the head on my redmax 2600 to get more line out, it wouldnt come out so every time i would have to take apart the head and separate the line that had "melted" together. i had most of the problems come after doing a long fence line or edging (high rpm's for extended time) i am using echo cross-fire 0.95 and a redmax 2600. any ways to get rid of this? i hasnt happened since now. does the outside temp effect this???
