As long as you followed the procedure, it is what it is. Once you start up you'll know, or maybe not, if your still unsure and don't have a trained ear as to what your listening for, do it while it's running at idle. Loosen the adjuster and then push or tap on the adjuster rod (use a longish narrow screwdriver) , if its out of adjustment you'll immediately hear the cam chain go quiet, otherwise its fine. It's not uncommon for the adjuster on the 350/400 to stick, lack of maintenance, the chain stretches and gauls the pivot point on the adjuster or the lock bolt that sets the adjuster rod gauls the adjuster and it refuses to slide in its bore. Either way, a tap is what is required to free it up.
