The reason a common Briggs and Stratton can not run so slow is the magneto ignition, clearly replaced in this case.
But, yes, large flywheels and an electric ignition and it can be run very slowly, without a load.
Although the lubrication system is of the splash type, so one will want to add extra oil.
This might be a useful design for a standby generator, in place of start and stop, run One or both of the flywheels could be magnetized to produce a limited amount of power at idle.
whats powering coil, is it 6v or 12 v coil, powered off primary winding of OEM magneto or wind your own on magcore, ?? can't recall ever seeing B&S with points
@sewallm60 : This man owns about 40 flywheel engines. Some so big that it took tractor trailers to haul them in. He makes use of the starting fluid on some of those.
@wvsky nothing serious more of a dig then anything his shop is so clean i wouldn't expect anything to be weaned on fluid he had. do you have any of his others posted never mind i see'em good job
i took a tecumseh engine and put a 35 LB olympic weight on as a flywheel, and then made a hit-and-miss mechanism for it. i gotta get it going again and make a vid
Have you thought about the risk of blowing up the flywheels from overspeeding? Depending on what they are made of, you definitely are at risk by a flywheel rim surface speed of 12,000 ft/min or even lower. That's probably no higher than about 3000 rpm.

What do you operate with this engine? It looks like it would make for a good trolling motor or generator engine.

hope its not slinger lubed... if it is then DX (slinger lubed ones need enough sped to splash oil all around)

-The engine on the video is a throttle governed engine, it has no such a mechanism like a "hit and miss" engine has.

@robinhooodvsyou thats is more or less a hit and miss mech by the way you said it but have it your way

@0812201 the battery wire is going to the cover behind the flywheel, and using the factory points to break the spark.

this thing is pretty cool, but it can't go as slow as a real fly wheeler. those suckers can run with like one pop per 4 seconds

A 12" wheel at 3000 RPM has a surface velocity of 107.1 mph, or 9,424 ft/min.
I wouldn't rev that thing too high. :)

@flash178 Agreed. The lateral runout isn't appealing to the eye. But for one that isn't clamped down, that's a sweet runner.
