Help with Fairbanks Morse Z 1.5hp

I am new to the hit n miss and need help with my new engine. I think it is a 1919 fairbanks 1.5hp but the numbers are rusted and gone. The tag says fairbanks z 1.5hp 500rpms.
It has no spark plug and points are in the head, carb is mounted on the bottom and has a round bowl, spoked flywheels.

Re: Help with fairbanks z 1.5hp

hi,

welcome aboard. there just like potato chips, soon enough you'll be on the hunt for another. what you have there is a 1 1/2hp farbanks morse plugoscillator, you are missing the magneto. it has what is called an ignitor.
here is a video of a running exmaple (not mine):


and another



regards
jordan

p.s. maybe one of the moderators could move this to the main forum so it gets more exposure?

Welcome aboard, The OLD IRON BUG BITES HARD. I also have a 1 1/2 hp plugoslatior, Picked it up last year on a trip to Washington. Very smooth running engine, Good luck finding the mag. This has become one of my favorite engines in my collection because of the way it runs

you're in luck, you have all the parts that are hard to find. The mags are easy to come by. Call one of the page sponsors like Rudy at Adrians Magneto.

Thanks to all that have replied. I am looking for some type of diagram for it I really need one for the valves and push rods, timing control. The bowl on the carb is rusted out so if anyone has any suggestions please let me know.

I was going to post a video of mine but Jordan already did....

mine is the one in the first video. My cup was missing also, you will not need it to run the engine. I made a new cup for mine but it's just there for looks.

Like Jim says, the magneto shouldn't be hard to find at all. These are very nice running engines and I was told they were only made for about 6 months in 1919. They're not real common. Mine is the one in the second video that Jordan posted.

Here's another video of mine.

The cub you mention is likely just for gasoline priming/starting of the engine and would be helpfull for running on less refined fuels like kerosene or dizel. If you are planning on runing the engine on Natural Gas (propane, methane, etc), gasoline, or naptha this pre-priming is not nessasary and I would basically do what needed to be done to make the cup look good. Basically it just allowed the engine to get hot enough that when switched over to kerosene or similar the cylinder was hot enough to vaporise the less refined fuels making for a more effective fuel air mix. Nice little engine really. Belive it or not the mags for this are not too hard to come by. Of course like alot of things there seems to be an inverse correlation between how badly you need a specific part and its availability. The plugoscillator was kind of like FBM's awncer to the Webster magneto. Ie they wanted to acchive the same reliability and simplicity of the Webster but in thier own design. The result was something that looked kinda like one of the old rotary mags in an elaborate bracket set up. FBM was one of the first companies to try to use thier own specific mags rather then generic ones... likely in an effort ot keep more of the buisness thier buisness so to speak.

The Plugoscillator was not an FM design, but was designed and built by Sumter. It was their answer to the Webster Tripolar magnetos, and was a Sumter rotary low tension mag adapted to impulse operation. FM used Sumter rotary magnetos on earlier engines like the FM 1 1/2HP headless, and went from the Plugoscillator to the Bosch AB 33 for the spark plug engines before switching to their own design high tension mags.

cpl1081, you can check the valve timing by observing the position of the crank shaft while turning the engine over by hand. The flywheels turn clock wise when looking from the ignitor side. The exhaust valve should begin to open at about 35 degrees before bottom center on the power stroke, and should close completely at TDC or 5 degrees or so past TDC on the exhaust stroke. Small adjustments can be made with the adjusting screw in the rocker or push rod, but larger adjustments will have to be made by moving the timing gear. With the crank throw straight up in the 12 o'clock position, the nose of the cam should also be pointing straight up.

to Jim and Mike,

i hope you don't mind that i reposted your videos, i figured i'd track those down and put them in this thread as i remembered that both of you had these engines and had videos on youtube. this way you could give the gentleman some first hand knowledge about these engines because i don't have one to reference.

regards,
jordan

Not a problem at all. Sharing info is why I put the videos out there in the first place.:)

My son has the same engine, he is trying to get it working for a year now. the head springs are not too hard - Starbolt has them. The other springs are difficult, and that is where I am stuck helping my son. No luck yet.
