KD4 dates to 1946.,,,3/4s of a century ago. Repair manual is not essential and not all that common.
What is condition and what are the problem(s)? Several members have
been there and done that with the Little Mercs. Illustrated parts posters
are on this site with prior threads.
Love the Little Mercs
edit, Your KD4 is very similar to this KE4 powerhead I am working on.
