Why are these things so dang hard to set all the way back down into that lil cup area... i put alil mercury grease(4-2-C) stuff or whatever that stuff is... but that said, i completed my 100 hour service myself and so reason i could not for the life of me get that thing seated all the way down... i guess i won't hurt to run it with it loose... all the connectors are snapped on tight.
