Which MANCO is this? And does it matter?

Hello all!

So, long story short...I work at a rural K8 school, and every year we have a handful of young guys who don't have a great home life, don't play sports, and are otherwise left to their own devices to get into all sorts of mischief (which you and I would have NEVER done back when we were that age....Haha!).

Enter our recent go kart acquisition....

I bought this bad boy sight unseen for a small crew of guys to work on. Once we had it in our hot little hands, I realized what a mess we'd stepped into. She needs a lot of work!

Most of the big pieces are in place, but there is still PLENTY to be done. Considering that I already paid too much for this little gem, I'm already backed into a corner and want to make this thing worth our while! It's gotta perform at this point - no way around it.

So to begin our journey down this gritty go kart path, I'm going to need a whole lotta help! So I'm starting right here...

What is this thing? It says MANCO on it, and she's got a serial number - but before we start ordering parts, it would be nice to know which model we're dealing with. Is this a Baja 200? A Dingo? And ultimately - does it matter?

It's got a Honda 5.5hp engine that starts, but won't stay running without a little feathering of the throttle. Carb looks newer. Missing brakes, throttle cable, seat is beat up, all four tires are flat, the clutch/torque converter is not functioning, the chain is off the drive gear (which also looks out of alignment) at least one wheel is chipped along the bead....BUT, the tires look decent. The engine does fire up. The seat is easily recovered. The frame doesn't look mangled and the pedals are there. I see potential! (I have to keep telling myself that because I'm in too deep at this point!)

In the past, my small groups have done lawnmowers, chainsaws, motorbikes, generators, boats and kayaks, even older cars - but we've never had a go kart! We know nothing at this point. We're all rookies in this realm. We need your expertise!

Here's what she looks like right now....what can you tell me about this thing?

Gimme good news....

Manco 285 and it does matter.. that's IMHO the best Dingo (nickname of said [and few other] model) you could have.

Yes the identical kart with the larger 9hp engine (289 ;)) is even nicer to have since it packs a bigger punch..
but swapping the engine isn't too big of an issue, is it? :D


I bet cleaning the carb of your GX and maybe adjusting the throttle cable afterwards
and the engine should be fine (Hondas are known for their almost obnoxiously long life span ;))

Now, it appears someone replaced the well working TC it came with originally, with a simple centrifugal clutch..
IDK if said person changed the gear ratio, but I doubt it tbh..
Soooo you mioght not be able to move that kart even if the engine is running nicely
just because of said ill move.

Easiest fix: get on ebay and buy a cheap series 30 TAV kit (3/4" shaft and likely 420 sprocket check with the axle sprocket to verify the chain sze)
will set you back a few bucks, but that's likely the best thing you could do

even if you still have the original jackshaft it'll still be the cheapest way to refit a TC
the slightly longer 5959 belt will be needed, but everything else can be used off such TAVkit

Looks like a Manco Dingo to me.
As far as getting your money's worth out of it, go karts are really terrible for that, from my experience. Parts add up pretty fast, but most people into karts enjoy tinkering, so the satisfaction is worth the cost.
If the frame is solid and straight, the rest is pretty much bolt on kind of work. Looks like it needs an exhaust pipe & muffler, it's a band brake setup, which is pretty easy, the clutch looks like it could be a max-torque or a Hilliard, both are serviceable, live axle is good, could possibly change axle bearings. Carb on the motor probably needs to be cleaned/ serviced.
Overall, looks like a fun project, with good teaching potential for the kids. And for you!

You've got the original and sought after original Manco wheels up front.
If it's one of those that's dinged on the bead, you can repair that with JB Weld.
It'll hold, I've done it.

Wahoo! Now we're getting somewhere!

I knew you all would know....THANK YOU!

Welcome to the stable, lil' Manco 285!

I'll post a few thoughts here shortly....

The carb looks to be new/almost new. PO mentioned that the carb was a relatively new repair. He also mentioned that the clutch had begun to wear out, so he was ready to kick it down the road. Not sure who swapped out the original TC. We'll do some reading, but why is the torque converter preferable to the clutch? Just curious as to the advantages.

We have no throttle cables/linkage at all. That may take some crafting. Looks like a simple plastic arm that moves the throttle on the carb. We may have to get innovative with that part.

No idea on the sprocket sizes; that will give us some things to chisel on. And while I'm on it....I'll see if I can chase down a 9hp engine! Haha! But honestly, if we can get this little 5.5 to come alive just fine, we won't mess with that. I don't think.

Not too worried about making a buck on this guy, but sure don't want to end up with $1000 in a $350 go kart. We don't really do it to make a buck, but we can't afford to take a bath on it. Historically, we've been VERY fortunate on our projects; we've not made a dime on anything - but we've not found ourselves getting KILLED on any of it either. There's no budget for these kinds of projects - just whatever I'm willing to throw at it - so at some point it's still a numbers game.....but as long as we can keep our head above water (or just breathe!) then we're all good with that. Haha. It's more about keeping the boys outta trouble. Too much free time and they start throwing rocks at the school buses and whatnot......

And ultimately - YES - it's super fun just tinkering around on stuff that doesn't need a computer to diagnose and $10,000 in tools to bring her back to life. I love this kind of stuff, and would be doing it anyhow. But I'm a tinkerer. Haha.

Hey - right on! That sounds positive! It is, in fact, one of the front wheels that has a busted bead. Guess we'll be hitting you up for some tips with all of that! Thanks for the heads up -

To figure out what sprocket you have, you can measure the distance between the high points on the sprocket. Have a look at these sites

http://jleibovitch.tripod.com/id240.htm

For throttle hookups, have a look at these pages

I would take the carb off and give it a good cleaning. Here are one or two links that might be interesting regarding that

As to gearing, could you give us the tooth counts on all the sprockets as well as the rear tyre diameter (tyre height). This will help us help you with gearing the kart properly

Shazaam. You guys don't mess around!

That's enough resources to keep us busy for quite some time...

I'll round up some details and get back to ya, regarding sprocket tooth count, shaft size (for the TC bits and pieces), and other deets....

---------- Post added at 10:35 AM ---------- Previous post was at 10:32 AM ----------

We def need a muffler. Anyone have any preferences? Does it matter which one we go with?

Anything will be better than the little pipe business that's hanging off her tail at this point!
