Man i have so many of those its driving me crazy. but here's another to add to the list.... The 17 Kaw twin on the w/b has alot of gaskets that seep oil and just generally worn alot of hours on it. good motor and good money maker but i got a sweet deal on this that i couldn't pass up. it's a 17hp twin kaw same as on my w/b but electric start and recently professionally rebuilt. So someday i gotta swap 'em out.
