2 dogs in post #3 hit the nail on the head. The OPE that are not perhaps the most popular ie solo/dolmar use walbo felt ones. Cost a bit more but put one in your hand next to a say a stihl and you will notice whats 'cheap' & what is quality. lt frustrates me that stihl which l do like and have many saws from have been slowly putting cheap Chinese parts in there highly expensive pro equiptment. lts not just the fuel filters either, on the 'made in Germany' saws you will find 'made in China' parts like their zamma carbs for example. The equiptment IS reliable and of merchantable quality but they are trying to get away with more and more of this. Kinda sad really....lt seems the greater a companys market share, the greater small savings are worth to them. They once built their name by selling top quality gear made from higher grade material, now they use their reputation and brand name to increase profit at the customers expense. lmagine if half the advertising budget went into R&D, the saws we so much love would be so much better.
