I have a QT16 (circa about 1972 ish) I have everything there is to have about the QT16 including overhauling the hydro pump. I don't know how to upload stuff or I would post it here.
If you can't get an original owner's manual ...... for the cost of taking it to the Office Max photo copy machine (it think it's like 12 cents a page here) and the price of a postage stamp I can make copies of anything you need. Let me know. > [email protected]
