hello, new to this forum, found it by searching for info on a prime mover l-1200d i recently purchased. anyway, i did find online owner-operator-repair and parts manual on line at the following link. i had trouble trying to print the manual all at once, it is about 138 pages, but if you print 10 at a time it works ok. here is the website http://www.minnpar.com/partbooks/Prime Mover/L1200.PDF
