I bought an H14 last night
It's a -02 so it would be either a 1974 or 75 since the appears that the -02 production run spanned both of those years.
Reason I got it was to use it with the EZ-Vac. The 1256 that I was using it with just will not lift the mower deck high enough and even with it raised all the way up, it cuts WAY lower than I like. I think that the 1256 will get the Haban Flail-Mo put on it.
It's rough looing and needs a bit of carb work. For one reason or another, when it's cold it doesn't want to start without just a wee spritz of carb cleaner. Once it's warmed up, it starts just fine.
It's not charging, so I think it may need a voltage regulator as well.
Other than that it's, mechanically in good shape. Cosmetically, it's rough, but does have good straight tin.
Of course, I have pics
