True, but it's still a very handy tool to have. I still need to get the port cover plates for mine.
they are cheap, the carby side one is about $4 from stihl and on th muff side just use a bit of rubber,(pull the muff off, take gaskit off, put a bit of 3mm rubber over and then put the muff back on and do it up tight)
