I notice robin subaru portable generators have ohv and ohc on the 2009 models.Is one more reliable or more expensive to produce??Why did they change for the 09 models?I see most generators use ohv engines.

According to Honda the GCV190 belt runs in oil as well:

"The GCV190's innovative combination of a compact combustion chamber, overhead cam configuration
and uniblock construction significantly reduces fuel and oil consumption as compared to conventional
side-valve engines. Honda's DuaLube™ System achieves full engine lubrication by combining governor
slinger paddles and an oil bearing timing belt."

I still wonder what they say about change interval though...

"I still wonder what they say about change interval though..." I'd venture to say the belt will likely last the life of the engine. Considering timing belts on automobiles are good for 90,000 plus miles, I'd be willing to bet that a belt designed for similar applications albeit fully enclosed and bathed in oil, on a piece of OPE will last a very, very long time.

The GCV designated Honda engines don't enjoy the heavy duty reputation that the GX designated variants do in my neck of the woods. Most of the  locals view them as light duty and not worth the time or cost to repair. The complaints center around cam belt failure and the expense associated with that component. If going OHC I would prefer a chain driven cam set up. If not available I would opt for an OHV.

The OHC Honda engine on my yard tractor is a GX series. I've not heard of any complaints about their durability. If belts are suitable for high mileage automobiles, I have no concerns with their reliability/durability in an OPE application if properly maintained. Time will tell I guess. Regarding your comments about the GC series engines belt failures. Could that be caused by low oil conditions?

Good question re: low oil. I will ask the next time I see the mechanics at the Local ope shops. There are two local shops and both said they didn't like the belt driven Honda's because of durability and repair cost.

Is it an interference head design? That might account for their comment that they are too costly to repair if the belt breaks.

By "interference" type I'm assuming you mean if the belt breaks, the valves may make contact with the piston(s). Right? I really don't know if it is or not. I've never had it apart. Don't really plan to either as long as all is well.

Right, makes a real mess-stems, guides, seals etc.
