Hello. Several years ago my father in law gave me the Howard he had used to till his greenhouses with, it ran albeit poorly. The mag was in rough shape so I had it rebuilt. Now I am having trouble getting the mag timed properly and am in need of some assistance. I would also like to learn where I might be able obtain any maintenance literature applicable to this machine which according to the data plate is a G24T, Serial # G2531572. I am determined to return this fine old machine to service but here in the States, Howard experts are few and far between. I am hoping that someone here might be able to get me pointed in the right direction. Thanks, Rick
