Getting tired of pulling on my echo handhelds. 3-6 hard pulls when cold and if it sits for more than 30 min, it's 2-4 hard pulls. Starts great when hot though, 1st pull every time. I have srm-230 trimmer and 230 stick edger, they have been this way since new. I've tried the echo synthetic blend 2 stroke oil as well as the opti-2 oil and there was no difference in starting difficulty. You guys have any suggestions for easy starting trimmers, edgers, and blowers?
