any Tecumseh experts out there?

[explorer]

I bought a go-kart that has a hm80 Tecumseh,
it is not the original engine, it has a place for a starter, so my mind is racing,
"how can I install a charging system?"
maybe a stator?
an alternator that runs off of the axle?
anybody try this?

I'm far from a expert but I do have a HSK850. I think their very similar. Mine came with a 120v starter.
I think you can put a 12v starter on. I'm looking too.

first thing:
get the model and type number from the engine, and find the shop manual for it
(thanks to google a quick roundtrip)

second thing: see if the original way is feasible for you to replicate!
are the charging coils present or not, is the flywheel equipped with the magnets for said coils.
and if any of the answers to that is "no" then what a used/fresh replacement part would cost.

And only if you don't have a solution then it'd be time to think about alternative ways to
install a charging system.. or more precisely..
to think about ways to install an alternative charging system

thanks Sid,
I have done all that, but with my marginal mechanic skills I'm nervous about taking stuff apart when it is in running condition,
right now I'm leaning towards a charging system that goes on the kart, then I can switch engines if needed and not worry about a new charger,

did you find or rig an alternator system for a kart?

thanks,

if it came with e-start it came with a charging coil...

or let's say: I have yet to see an engine that left the factory with e-start but without charging coils ...

no need to "take things apart" really... just inspect thoroughly..
a ring gear on the flywheel (peek through the vents of the shroud) tells you it's more than likely the correct flywheel already. (magnets and such installed)
a wire coming from the flywheel area running to where the starter would sit gives you a hint about a present coil... etc.

Sooo why bother fabbing up something you don't need?

PS I have a manual (HM80 is covered) charging system page 46ff

thanks for the manual,
there is not a pigtail coming from the flywheel so I'm assuming there is not a stator, if I researched and found a stator then I would have to install it (scary),
I might man up and do it,
BUT an alternator running off of the axle seems really cool,
I was hoping someone knew of a kit or something,

thanks again for your imput and esp. the manual

Well since you have a reduction from the crank to an axle, you need to overdrive the alternator from the axle to spin it fast enough.

Small Sprocket on crank, big sprocket on axle.
Big Pulley on axle. Small Pulley on Alternator.
