Ok here is my problem. The 555 i bought new in feb/2011 has had a stumble off of idle and or stalls wheni give it full throttle to do my next cut. This only does this if the saw has idled for 30 seconds or more . I have taken it back to the dealer 2 times and they say they cant get it to do it .
The third time they finally got the computer to hook it up to and found nothing wrong . I noticed the fuel line coming out of the tank going to the carb has a sharp bend to it ( almost kinked shut ) could the saw be calling for more fuel at idle and loading up until i give it gas and stumble? I do have the new updated fuel line that was in the service bulletin but havn't put it in yet. the saw runs great at full throttle . I am fed up with the dealer i got it from at this point. I run sunoco 98 ethonal free with stihl ultra at 50:1 and hve tried other types of fuel also. Thanks for putting up with my long post.
