Starting a Rare Fairbanks Morse 3hp 'Z' True Hit and Miss Engine with Buzz Coil Ignition

- A rare auction find! Fully restored but will it start? Watch and find out!
This video is for the true small engine aficionado as I go into great detail about the unusual buzz coil high tension ignition and the fly ball hit and miss governor. Very few of these 1923 engines were made and even fewer still exist. - บันเทิง
It's so great to see this video!! I found [and still have] one exactly like this one in 1972. Way before the internet, which brought me to this. I haven't had mine running for years but am going to get it running again and hope to power a line shaft machine shop I put together many years ago. I use a big electric motor to run it all the time but I have a smaller throttle governed enclosed crank that I've used before. I just want to get this out and running again. Mine still has the tin box with the knife switch and a model T coil like this one. When I dragged it out of a junk yard in 1972 the rocker arm was broken and missing but I figured that I could make something to braze on that would work but it would be a lot of trouble and thought. Imagine my happiness and surprise when in cleaning out all the junk in the water hopper I found that whoever broke the rocker arm off in the past was thoughtful enough to put it the the water hopper to be found! I brazed it up and it worked great. I had it running for years [after much trouble without the help of the internet] and with a load on the flywheels it would keep certain RPMs pretty well. I need 250 RPMs on the main shaft so the spring trick I just learned will most likely to come in handy. That and a bunch of pulleys. I'm so grateful to see this! Mine also has the same [but weary and rusted out] gas tank too. I now see one can even buy a new gas tank! Who'da thought?
Thanks very much. Let me know if I can help!
Thanks for sharing. Love this old stuff. We didn’t own anything like this, but my dad took me to local antique tractor shows and events. Ironically, we also had a Model N railroad layout we tinkered with.
Very cool! Thanks!
Great video, lots of detail!
That is quite a find!
We recently bought an engine that needs a buzz coil, nice to see the information.
Weird Detroit Engine Works 3 Hp 2 stroke reversible vertical boat motor with a cooling water pump.
Glad it was helpful! I learned a lot working on it.
I love your engine! Great find !
Thanks!
Your Z is a beautiful engine. I myself rebuilt a 1 1/2 1918 Z compression was not high due to pitting on the cylinder. I had a machine shop bore and sleeve it. The points were modified from original and now it’s a running machine.
Thank you! I'm getting ready to put this one a pecan cracker!
very nice.i used to have a z 1 1/2 throttel gov.used to boil
eggs while craking corn.
That's hysterical! Took me a second but I got it!!!! Thanks!
Amazing-- thanks for putting another informative & significant historical video together, Jay-- so great to learn about these vintage engines.
Thanks for the video. I have a 1917 3HP Z ENGINE which is throttle governed with a plug oscillator , and was not aware that Fairbanks Morse made a Hit n Miss . Never to old to learn .😉 !
Glad it helped. Thanks for the comment!
Yet another superb video.
In a moment of weakness.... Laynie understands. 😂
Careful around that buzzbox.... don't get "bit"!
You done did it again! Great Stuff! Suggest you keep the "Run Slow" spring installed. It better matches your own speed...
Another fantastic video and project!
I can't wait to get mine going, thank for the inspiration.
Thanks for the great explanation and demonstration of a unique governor mechanism. I wasn't aware that FM ever made anything but throttlers in the Z series.
Thanks! I really learned a lot myself!
Thank you for sharing!!
Great work on that rare engine !! ......A good, clean Contacts, connections & wiring Properly Adjusted buzz Box should run Good off 6 volts.....Sometimes the Internal 0.22 uF 400 volt Condenser (Usually Buried within the wood Buzz box) goes "open" & Reduces the spark Intensity......New or Rebuilt boxes are available.....
We really had to clean those contacts Tom. I've used some vibrators in amateur radio equipment and often VERY aggressive cleaning is necessary. After running the engine a while AND having to readjust the contacts a couple of times I was thinking about trying it on 6 volts just to see. The cap was replaced before I got the coil by the way. Thanks very much for your comment!
Love it Jay. Always wanted a hit and miss for our farms sourgum smasher. Something fun to watch other than a tractor.
Check out some of my other videos! We use one to make ice cream and another runs an oil pump jack!
I also have one of those, it's twin a 3hp throttler with the AB mag...... And a 2 hp dish plan from 1923
Very informative video. Thanks
I wish they would make equipment half as good as this tofay
You will need to adjust the chock or / and the main jet. As you change the engine speed. To keep it dialed in to one hit between misses.
This is really nice, Jay. Thank you for sharing your adventures.
What? No Morse code whilst testing the buzz box? 😿
Good call on the choke issue. I would have suspected fuel delivery. 👍
I have extreme curiosity about the hit-and-miss mechanism. I will look it up to see if I can “see” it.
I actually did test it with a Morse key.... gotta be careful as there is a LOT of current! Only two things will keep and engine from starting... fuel delivery and spark. Of course, adjustment of same is what makes them RUN!! Thanks!!
What a pretty red engine!!!! I'm sooo sure Laynie loves it!!!!
Of course!
I've been looking for a good hit and miss engine, I have a idea for a good business that I can use one for
What was the point of the hit-and-miss firing cycle? Fuel consumption?
I think it was cheap to make and maybe used less fuel.
What were they used for?...
I've got one.. the mag hits on the workbench.. but not on engine
My engine does not have a magneto! Spark is generated by buzz coil. For a magneto engine, make sure your magneto is attached to the engine with a good electrical contact to the frame! ALL electric circuits require two paths, the "spark" from the mag and a return to the ground (chassis).
Of course make sure the timing is right.... but you should get a spark at some point in anycase.
Any help??
Jay.. thanks for replying.. I think the timing is right.. I lined key on crank with dimple on small gear.. that leaves valves closed... Right?? Still the mag will eat you up on bench but nothing at all bolted on engine.. I can lay mag up on top engine.. it will throw blue spark.. soon as I bolt it down... Nothing
Any help would be greatly appreciated... Thanks Jay again for replying
Type e mag
I would have took the old spring 2 the hard ware store and matched it up 2 the closest I could find even the same spring tension also 😊😊 OMG 11 1O 2O23
Yup! Good hardware stores have boxes with a variety of springs to choose from.
