they probably get sick of reading all of you whinning about these caps. how many threads has there been on people whinning about how terrible these caps are. i've got posts on all of them. the problem with the caps seems to be a hit and miss situation. some people have trouble and others done. some like them and some don't i'm one of those that haven't had any problems and i love the caps. i wish i could replace the caps on my older stihl equipment with these.
