Default Monarch Engine 1 1/2 HP

According to the tag, this engine was made by Nelson Bros. for Wallace Corconan, Portland, Oregon and it is a hit and miss. Can’t seem to find any numbers where I believe the serial number should be. It has a spark plug, but no sign of a device to supply the electricity. No sign of a gas tank either. This is one of the engines that I drug out of the briers and thought to be complete. The crank bearings don’t have grease cups, but only a “v” in the bearing cap. Do you just put grease in this? Can somebody help me out to find information about this engine? About the age? Ignition system, timing and so on. I’m a beginner and looking for help.
Thank you
Ken Adamson

I don't know much about the Monarch engines, but how familiar are you with gas engines? I'm just wondering if it may have a magneto and or gas tank on it but you don't recognize them? Remember that lots of engines had "hidden" fuel tanks that were inside the base of the engine where it wouldn't get damaged. As for the bearing caps, they have an oil tray. I beleive there should be a wick in there and you just fill the tray with oil and it wicks the oil to the bearings. Refill as needed.

The serial number should be stamped on the face of the exhaust side flywheel if it is built by Nelson Brothers. The spark plug is most likely a conversion from an ignitor. Some of the Nelson Brothers engines had the gas tank in a cast sub base, and some just had a tin gas tank. There was good thread about Nelson Brothers engines a month or two ago that had lots of pictures. Check the archives to find it and see how closely your engine matches. Keep us posted on it and great find!
