not sure WHY motor is in need of a top end, but if SUNK< or??
there is NO WAY to clean the inside of a motor by flushing
flushing is ONLY a gamble, some times it gets enough out to run for a while, MANY times it doesn't

SO< honestly, if your looking for long term life out of the motor, SPLIT the cases, all the more so NOT knowing what all has been done to the motor before you had it
might have been sunk MANY times and old owner ditched it knowing so!
just a top end, and you can soon have wasted all your time and money on a top end , as will be back to smoking or worse real soon!
