Wow, that mouse house is impressive. Mouse urine is way more destructive than the mud dauber nest.
Here are a couple of pictures of "Daubey" a 1955 Evinrude 15hp Fastwin. It was given to me and it was in a barn that had been on a gentlemen’s property for years and years. The barn was pretty old so, how long that motor sat out there was unknown to the owner of the property. One of the guys I worked with knew the owner from their Church. The owner was telling them of an old motor he found in a barn years ago when he purchased the property. My buddy told him that he knew someone who liked to work on old motors. The owner said, tell him to come pick it up or it was heading for the land fill. So, I went get Daubey and was surprised find a to mud dauber resort under the hood. Before I watered it down, I removed the carburetor and sealed off the entranced to the crankcase with a cork and masking tape. I was very careful with a hose and water to remove all those nest. Immediately after the cleaning I removed the flywheel and used a lawn blower to dry every nook and cranny. I removed the ignition plate, clean, dry, and put new coils because the old one were cracked. Cleaned carburetor and put a kit in it and put it back on. I then changed the fuel hoses.
If memory serves correct, it had 115 psi upper and lower.
Daubey, came alive after the 2nd or 3rd pull. Ran well in the barrel. Thanks reminds me, I need to reseal the lower unit, it has a drive shaft and shift seal leak. Daubey is my favorite story to tell, sorry I went on a bit.
