Poking around Harry's one night and came across a Hvid I wasn't aware of (and there are a lot of those!), a Pohl.   I had read in Wendel's BYB that there was a manufacturer in Vernon and it tweaked my interest for a couple reasons: my grandparents lived just over the hill from there and I used to help Uncle Dave shovel out stalls at the track when we were kids.  I emailed the gentleman who was credited for the photo and he was kind enough to send me several more of photos of this interesting Hvid and a little bit of its history as well.
Here's an early photo of it not long out of the barn. It appears to be in decent condition...of course I thought the same thing about my 8hp Thermoil too! It resembles a St. Mary's HO somewhat but as you look through the other photos you'll see some huge differences. We'll start right now with the enclosed crankcase. According to Woody, it is not splash-oiled but he may convert it to cure some crankpin oiling woes.  The water hopper has a plug in its but only the one that I can see...not sure what it's for.
As Woody puts it, "One of the previous owners did a cosmetic restoration but I had to get it running."  He had the crank professionally rebuilt at a diesel shop to repair some damage there.  Craig Prucha reconditioned the piston, cylinder and rings.  To top it off, Wayne Grenning rebuilt the injector.  That is a ton of work to be sure!   Something else that is interesting is that the patents listed on the tag are Brons patents and also says that it was build under license from the R.M. Hvid Co.
Lots of neat things to talk about in this frontal view.  Let's compare it to a 4 hp St. Mary's HO Hvid. The first thing that strikes me is that the mechanicals appear to be on the opposite side from what I'm used to.  The exhaust valve actuator arm and air inlet valve arm are on the left while the fuel inlet arm from the governor is on the right. The air intake is also rocker arm actuated unlike the St. Mary's 4hp HO which has a poppet valve.  The small arm on the exhaust rocker arm hinge pin is a compression release to help make starting easier.  And I wonder what those square head plugs are?  They sure are different!  Note how the nicely reproduced fuel tank sits on skewed mounts, it is much easier to look in the water hopper on this than on the St. Mary's.  The drag link pivot is a separate piece mounted on the head unlike the St. Mary's which is cast as part of the hopper.  One thing that strikes me as being similar is the air intake pipe underneath actually extends underneath the base.  The design was intended to access an air mass that was potentially less contaminated with dust and such but Woody's comment was that it was tough to choke/prime with it in place so he usually runs without it.  He also mentioned that he didn't think that Pohl engineered these in house but rather may have retained St. Mary's to handle the design.  It certainly isn't beyond belief, there appear to be some similarities.  It sure is a good looking engine in any case.
And yes Virginia, it runs!  Looks like a normal flyweight governor on the flywheel muchlike and Associated.  There is also an integral handle in the wheel rim for hand cranking.  You can see the hole underneath the cylinder where the intake would go in.  You can see the enclosed crankcase a little better in this shot and can tell there is no mechanical oiler.  Those seemed to fall out of favor with everyone later on and they just used appropriate cylinder oilers.

In any case, thanks a ton to Woody for sharing photos of his beautiful engine and some of what was involved to get it running again!
