stihl 041..runs good till it gets hot,then it doesn't want to throttle up,it stalls,wont take gas...or you have to coddle it to throttle up,stalls...i have replaced diaphrams..i have been running hi-test for about 5 years..a little heavy on the oil mix...i bought saw new,it's never been worked on and it's not a production saw.
