I'd take the time to restore an engine like that. I'm getting an old villiers of a friend, lucky to do 1000rpm, and I'll be restoring that to factory specs.

Are these old engines worth a lot of money?

Kartless....
Not a lot(that I know of, Russ wil probably prove me wrong), but that isnt justification to mess with one.

...oh yeah....!
You don't know how many used corn-dog sticks I've lost down sparkplug holes.... that's how I ruined Grandma's Plymouth!

Only if it's NOS (New Old Stock), and would have to find the right buyer. Check Ebay. There's still tons of them (used) out there.
Example of 6s:

Example of 5s:
Ebay 5s
6s tends to have more value because of it's 5/8" shaft.
The 5s has a 1/2" shaft and for this reason is not 'kartable' unless a 1/2" bore direct drive sprocket is used.
Nice thing about these engines is, if they through a rod, no damage will be done as block is cast iron.
Can't say that about their aluminum counterparts.

If the rod throws hard enough it will punch a hole even threw cast iron.

Not on these engines.
Never happened to me in at least 6 'attempts'.

Kartless....
They dont build stuff like they used too.

Hmm....I think I'd be able to get a nice hole in the block. Then again if they are so beefy the rod wont be breaking anyway.

In that case, it seems better just to get a cheap 5/8" $30 Max-Torque 11T clutch for it, and put it to use.
As far as power goes, is 25Mph a good speed to expect from it with the right gearing?

Sounds reasonable but It will take you a while to get there.

My 3.5hp 2-stroke cast iron tec got my kart to 25, and it would go faster with a decent exhaust and if I modded the throttle so it opened all the way up.
I think a B&S 3hp will get you to 25, but it won't have very good acceleration.

Rods in these engines are not 'beefy' and will break just as easily as any other stock rod. My point is, there is little (if any) collateral damage.
Yes, about 5 seconds.

Thanks Russ. 5 seconds really isn't a very long while, especially if used on a bicycle trailer, I don't want to take off too fast. 10 seconds or so would even be fine to get up to speed.

The first pics are simple, as it was new, then later on, I added ball bearings, more steel, and changed tires. I still have to upload more recent pics with it painted black with a new cargo rack on it now.

Holy cow how long is your thread on that site about the trailer?

22 pages.
It's just like a go-kart that attaches to the rear of the bicycle.
It hauls stuff too, BIG plus for a bike!
Now that's been done, I'd like to use my B&S engine to make a slower, simpler, and less expensive trailer.
I figure that if that engine can push a bicycle, then it also should be fine for the go-kart that the thread starter wants to build with this type engine.
