Lawnmower idle question

[jakdedert]

Yes the earlier Techumsehs did have a problem regards to burning oil.
They were built terribly cheap way back.
And yep, the earlier B&S engines were built like a tank.
The problem with using the older Briggs horizontal shaft motors for
go-carts or minibikes was they had low rpms and not much torque.
The ones they marketed specifically for that purpose were setup tp
spin a bit faster and had higher compression.
You could fudge a bit with some of the 3hp models by resetting the
mean idle on the govenor springs and either rejetting the carb for
quicker response or replacing it with a bigger throated one so the
engine could breath a bit better.
Using a low hp engine like a 2 or a 2 and a half you'd have had to
change out the drive sprocket for a much larger one to make it an easy
pull. Which of course would have made it as slow as a turtle.

Which it was...it could barely get out of it's own way <g>.

Just a thought but if you want to make that scooter fly try finding a
Honda or Toyo horizontal shaft motor.
You can usually get them off pressure washers with bad pumps as those
motors can't be killed short of running them with NO oil and they are
usually high horse powered, 7 to 12.
These motors have high spin and good torque and can get that bike up
to 50mph.( I'd done that for so local yahoo a couple years back for
his camp mini-bike. Saw him last month and he had a pronounced limp so
I guess he got all the speed he wanted.)

You must've missed the part about the sixties. That kart is long gone, now.
I think it crashed when we were pulling it with a horse. Riders (both the
one on the horse, and--thankfully--the one on the cart as well) got off for
refreshments, and the horse decided to make an unscheduled run. I believe a
fence post did it in...stopped the horse, though.

Kids. Somehow I wonder how we survived.....

Hey you think that's crazy.
When we were youngsters we hijacked my older sister's roller skates
cut off the boots and used them to "body skate".
Simply sit on the skate, then lie flat out with your feet supsended
straight out in front of you (inches above the ground) and head off
down that big hill.
What made it dangerous for us was that big hill was a street with
several stop signs along the way.
Sure made alot of cross traffic stop and do a double take, to see a
kid sailing down the hill on his ass at about 30 miles an hour.
Of course the bottom of the hill took a sharp right turn AND had a
telephone pole on the corner.(made for lots of scrapes and bruises)
