Hi everyone. As per one of my recent postings, sticky valves were driving me insane to the point that I was ready to, really, give up!! However, I took the suggestion of someone, and Im sorry...I forgot who gave me this tip....this kind soul told me to clean the valves, and casings real good, and only apply 1 drop of oilon each valve, and by hand, cover the enitre valve. I figured, what the heck....Ive tried everything else. So I did, and VOILA"-it worked!!!! I tried this, I dunno, about a week and a half ago, and my valves are sliding right along!!! And Ive NOT oiled since, and everything is working fine!!! I never thought that only 1 drop would do it, but it has!! And thanks to Ken Saul for a great oil, Ultra Pure!!!
