Listeroid killer from B&S

Here's the newest entry into the slow speed (500 rpm), dual flywheel, single cylinder engine market.
Look out Listeroid.!

The torque must be awesome, did you see the size of the baseplate?

I'd like to see that puppy hooked to an ST7 or an ST10 !

too cool!
i guess it proves the old adage

where there is a will there is a way!

makes you wanna build one don't it?

That's an old 2 1/2 or maybe 3 1/2 hp @ 3600 rpm. I doubt that at slow speed you would get much usable hp out of it.

i figure it might be good for a quarter hp or so, not much but if you don't need much
it might be a fun little engine

certainly can't put out much power, because it has no cooling system left

so it has to dissipate maybe 300watts/hr or so

i guess a muffin fan might be pressed into cooling duty, but there goes your hp

That's what the fella needs for his cancer project, an old motor with substantial flywheels.

Cancer Project???

Ok, I'll bite.

So what sized 3600 rpm gas engine would I have to start with to get 6.5 hp at 650 rpm? 
And what will happen to it when I run it under a full load with my Listeroid flywheels?

Bent crank, right?

[vdubnut62]

Bruce, I would figure on having more problems out of the big end bearing than the crank.
I would really be something to have a casting available to build your own using maybe a 5.9 cummins piston and rod, or even one of the big boys....     Not sure what to do for a crank though.
I've even thought about sawing an old 2cyl Deere engine in half, but I believe that is a little above my skill set.
