I recently bought a used rig with two hot water machines on it. The one just needs a fuel pump for the burner, it runs great with good pressure. The other stalls under load. If i turn the pressure regulator down all the way its fine, but if i turn the pressure up it wants to stall. Is this a problem with the unloader or is the engine worn out? Its an Alkota w/16hp vanguard. By the way i love this site, been reading for a few years, but this is my first post.
