A Little More Work on New Bridge

I accomplished a bit more work on the bridge yesterday and then shot a few photos.

I decided to add an on-off switch for the grade crossing signals rather than using the on-off switch on the battery packs.  Adding this on-off switch provides far easier access.  Actually, I decided to do the same for the street lamps also.  In this photo, below, you can see the new weather-proof push button switch for the grade crossing signals (the black button next to the big red button).  The red button is used to activate the grade crossing signals...  push and hold to activate...

I installed both grade crossing signals.  Routing the wiring was a bit difficult for this front signal though.  It required a few holes and a 12" long drill bit!

The street lamps are in place temporarily to see how they will look.  I think they'll work just fine where they are placed in this photo.  The bulbs and the tops of the lamps are not installed yet.  This was just to see whether I liked this location for the four street lamps.

Here is looking at the bridge from the back end...

Again, a view from the back end of the bridge.  I'm not all that happy about the lamp post on the right partially obstructing the grade crossing signal but this will work.  I've seen worse in real life!

I still need to install all the electronics that will control the grade crossing signal flashers as well the electronics for the street lamps.  One thing at a time though.

I set aside today to mow the lawn.  It needed trimming and mowing and that typically requires about two hours of my time, at a minimum.  I had some lawnmower problems so it ended up taking far longer today.  

The engine is running a bit rough but after about ten minutes of running, it starts to run so rough that is almost stalls.  I think this is a sign of a bad spark plug so I pulled the spark plug, cleaned it up and gapped it...   after running for about ten minutes, the problem returned.  The next step is to replace the spark plug so I ordered one.  

While I was working on the lawnmower, I cleaned the carburetor again.  I was also still wondering about the condition of the fuel line.  The first step is to replace the spark plug so I'll do that when the new plug arrives.  Hopefully the new spark plug will resolve my problems otherwise I'll need to tear down the engine.
