I replaced a NEW carb on stihl trimmer and tuned it (somewhat) stays on but when I give it gas it stalls.. could it be a faulty carb? or what can I be doing wrong!?(unit is 7 yrs old) gas is fresh and good mix
Agreed, especially since it was doing the same thing with the old carb on there. You may be better at tweaking carbs than I am but to me it's not easy even if everything else is perfect. I'm having a similar problem with a blower but there's no hi/lo needle valves to tweak. I think I'm getting it sorted out though. Good luck!It probably does need some tuning, but you can't do that correctly until you are sure that there are no air leaks and fuel is always getting to the carb.
