Hi Folks, I am looking to decarb my 200 ho (E200FHLSOR), serial number, (05078198). What is the procedure, without the Strader valve that I was used to on my Old Johnie? I currently have 157 hrs on this engine and use Carbon Guard almost every time I gas up. By this I mean sometimes I run out and forget to buy it before I gas up the following weekend. Also I use XD-50 outboard oil exclusively, and try to use fuel cleaner at least once a year. Any and all help is appreciated. Thanks, Dave
