Please help, engine spins backwards

[FoxMccloud]

Hi, i have put a new engine on my manco dingo go kart. My friend who use to help me with it fell off the grid. So the issue is that the engine has to be mounted backwards because of the break on the left side. If any can help, it would be very awesome if you would share your assistance. There are some pictures attached below.

could you disassemble the axle and reconfigure it to fit the new engine the way you want it? it would mean moving the breaks to the other side most likely, and that would probably require access to a welder. hopefully you have one?

LOOOL

Sorry, the engine is spinning the right way round, you just mounted it backwards (the cylinder has to point to the rear of the kart!)

The problem you are having is a missing part!

The Dingo you have came with a torque converter setup, that had an external jackshaft (plate mounted under the engine)
Said Jackshaft extended to the opposite side and had the sprocket right above the sprocket.

like in this manual

I don't know your exact model of course (dingo is NOT telling I'm afraid)

but it'd be alike at least the Torque Converter Jackshaft setup

PS Bad news: you are likely going to NEED the Torque converter as well in order to make use of the Sprocket at all, otherwise the gearing might be too high and you'll burn the clutch!

Hi, I know the engine is mounted backwards. But it's spinning in the wrong direction in its configuration. But this is really the only way I could mount it. The breaks on the left tale up all the space for it. And I don't really have access to welding tools. But they are available if I absolutely need them. Also the sprocket issue. Couldn't that be solved by just getting a smaller one? But there would still be the problem with it having to be mounted backwards

You need to get the jackshaft with the Torque converter. No way about it. The ENGINE IS SPINNING THE RIGHT DIRECTION!! You have the engine on backwards to the way its supposed to be mounted. The Torque converter was part of the transmission and will help with your gear ratio problem. Get the proper parts, stop half-assing it by flipping the motor around, and you will get a properly working kart. This ain't a two stroke, you can't just run it backwards.

You don't need a torque converter per se, but you will need a jackshaft that runs across the frame to transmit the power from the left side of the kart, where the engine shaft belongs, to the right side where your sprocket is.

They sell standalone jackshaft brackets that bolt down under your engine. Get one of those, a piece of keyshaft, and 2 sprockets, and you're set.

Or you can stick a torque converter on that same setup.

Also the sprocket issue. Couldn't that be solved by just getting a smaller one?........

No, you will then be making it worse. Without a jackshaft like you have it now, the sprocket is already too small. You will need a bugger one. A MUCH bigger one (like 72 tooth) It's no use thinking about that though, because you need to turn the engine around.

I highly doubt your engine is turning the wrong direction. When you are facing the clutch, which way does the shaft turn? Clockwise or counterclockwise? I bet its counterclockwise (which is the correct way)

That's sounds like a easy solution, I will look into that. Thanks.

I know the engine is spinning the direction its designed to, it just spinning the other way I need it to. And I know that's because of my error. I trying to see if I can get the jackshaft for it, I don't think it ever had one since I've had it.

Don't be so critical, your attitude isn't helping.

There is another option...

There are companies that sell flywheel end PTO stubs for electric start engines. I've seen them for the predator 420 and 670. They are necessary for some lawn tractor repowers.

I don't know if you'll be able to find one that will fit your engine specifically, and they are not cheap. But they are out there. The downside is if your engine is equipped with a recoil starter, you lose that. However on some engines, the flywheel end bearing is less substantial then the PTO end bearing because it doesn't normally have to support the overhung load (engineering term for side load applied to an unsupported shaft end) of a chain drive system.

Okay, I'll look into your solutions. Thanks for your informative assistance.

Is that a small block or big block clone... Hard to tell on those pics...

I've looked for years for a small block stub shaft, shy short of making a new one. But that will have to act as the flywheel nut...

Its a small block clone. If you look at the pic of the starter, it says 7hp, which means that its a 196cc engine. And its a Duromax engine.

Its 212CC. You can find these on ebay

you sure?

Duromax have 212cc engines for their generators,
but the engines they sell seperately (namely the XP7HPE (the e is for electric start)) are 196cc
according to their own website at least
they do not offer the 212 without the generator

There's kinda why I asked... So many issues on just trying to identify what it is, in order to suggest a solution..

So a if you want a stub shaft for that.. Which looks like might be your only option for the minimlistic amount of work...
You have an electric start. So you'll need a piece of 1" shaft bored and threaded for the the flywheel nut thread, with grooves milled for a crows foot wrench to torque it down. Potentially turned down for what ever clutch size, and keyway milled... You'll also need a support bearing on that side to support the shaft.
