Any hobby or business that centers on obsolete and out-of-production parts certainly presents itself with problem-solving challenges. Our old engine hobby is certainly no exception.

Majestic antique gas engines have a unique mixer that's simple in theory and operation, but can be a challenge in gas engine restoration if it's missing or broken. An engine friend had such an engine sitting in his barn. It seemed a shame to have a somewhat rare, broken engine in its original state just taking up space for lack of a few parts. So, the Majestic engine winter project ended up in my care. My job was to get it running again and return it to the present owner. What follows is how I made a working Majestic mixer, starting with just the 'water faucet' intake breather.

This creation was entirely done without a lathe, although one step could have been accomplished on a lathe for appearance purposes only.

Step one: Do some homework on an original Majestic mixer to study its form and function. This was easily accomplished through another local engine friend that owns the same make of mixer. In addition to seeing the real thing, a photocopied Majestic owner's manual page showing the mixer's internal workings was provided by Jimmy Priestley, who's done a lot of research on Majestic engines. I was becoming convinced that a working mixer could be made without any modifications to the original breather, so if the original parts ever became available in the future, they could be installed in this engine.

Experts will undoubtedly notice that my solution varies slightly from the original design on one internal part, but let's keep our objective in focus: making a working mixer without the use of a lathe, keeping the original pieces untouched and getting the engine operational again.

The following items went into the manufacture of the mixer: a needle and seat from a John Deere 'E' engine and a check valve soldered to a length of 1/4-inch copper tubing, purchased from a major old-engine parts supplier. Any 1/4-inch brass fitting that has a male pipe thread and a hole in the middle is also needed. The needle and seat need to be modified since it's installed differently in the Majestic mixer when compared to an 'E' engine.
