To me, it's gold! (eBay find)

[cojaro]

I'd thought I'd share my find, maybe revive some lost hopes with it.

Well I was searching eBay for an engine for my on-going minichopper project, and, to me, I hit go-kart gold (I'm planning to build a go-kart after I finish the minichopper).

For only $46 and some cents, a 3-speed riding lawnmower transmission arrived at my girlfriend's house (not at mine because my mom would have a fit).

(ratios are engine driven sprocket : the sprocket that drives the axle)
1st gear: 4:1
2nd gear: 3:1
3rd gear: 2:1
And it has a reverse, whose drive ratio I don't know.

The engine-driven sprocket is vertical, but the axle-driving sprocket is horizontal. At last! I can use a vertical-shaft motor on my go-kart!

Keep looking around people, especially on eBay and you'll find something worthwhile!

Ok i got one of those on my mower. you need to get a hight reving motor to go fast.

With the right gear ratios that shouldn't be a problem if I can't find a high-revving vert-shaft motor

Do you know the typical top rpms of vertical shaft engines?

[robertdjung]

http://www.buywright.co.nz/enginesvertical10to30.html shows that it's probably between 2600, and 3600 or so.

If you get a 2 stroke th RPMs im sure would be higher. that look almost exactly the same as the one as i have. only my shifter is going off to the side.
