Huh? I've had my ehp 5100 for over 2 years. Filter stays amazingly clean.
Carb issues? Hard to start? maybe a little...
Easy to start, but still very temperamental, and it will not hold a tune.... I've gone back and forth with the 5100, some times I like it and some times I hate it. One thing is for sure, I've never fell in love with it like others on this site have. Good saw maybe, grate saw no. The 7900 is a different story, it's an awesome saw.
