Carter help

[bcrewcaptain]

Howdy all, this will be my intro and questions all at once.
I'm no stranger to projects and things with wheels and motors, however this has a few quirks I need a bit of help with.
Here is what I am dealing with.
Carter with 6HP Tecumseh

Picked it up for lets say a "good price"
Non-running due to fuel bowl and jet falling out when being bounced around with a 6yr old at the wheel.
Order a new bowl, new nut/jet, gasket and at least it will hold fuel in.
At first it would not run without the rear being in the air and the throttle held wide open. After reading a few posts on here, I pulled the low idle jet, cleaned that up and it seems to be idling just fine now. Primer bulb doesn't seem to be doing much, so that may need to be replaced down the road as it's looking a bit weather checked.
The issue now is what I need some help with. When I try to hop in it and go, it bogs down and will stall out if I keep on the gas, if I try to keep burping the throttle, it MAY catch. If I am not sitting in it, or if I get a push start, it will more that likely allow me to get going. If when moving, I let off the throttle, it is a similar situation. I am about 215 lbs as a ref point, it reacted very close to the same with a 185lb rider as well.
Note#1=the chain was rusty, real rusty, rusty to the point I had to free it with an overnight soak in PB Blaster and a LOT of working it back and forth. The chain now seems to move around both sprockets ok, but I will be replacing that as the wife increases my allowance.

Does this sound clutch related? I'm not familiar with how a kart would react. I'm used to gears and driveshafts, so this is new territory. The motor reaction for the world sounds like somebody taking an pushmower thru a hayfield when it bogs down.

Ideas anyone? things I can check?

Thanks! Jeff

More pics would help please..\

Sounds like it could be carb problems...

Is there any binding when you turn the wheel by hand?

The gearing may be too high also, whats the tooth count on the clutch, rear sprocket and tire diameter?

What pics would help? I can take whatever is needed when I get home.

I didn'tfeel any binding when free spinning when I had the rear end raised. With it raised it seemed to smoothly hit max rpms, without making any funny noises in the process. It just seems to act this way under load.
It does seem to pulsate a little now that I recall, similar to an older riding mower I had with a bad governor.

The sprockets are 12 tooth and 60tooth respectively.
I will doublecheck on tire size, but they appear to be the stockers, which would be a 16x650x8"

There may still be a carb issue, but a 5:1 redux ratio on a 6hp, 2 seat kart with 16" tires is not deep enough, IMHO. Perhaps it originally had a CVT and th PO changed it out for a clutch without regearing. We see this all the time.

Just had the wife check, that is the correct size tire that's on there, so that is right on the ball. According to the parts list, the factory parts included the Comet series 20"torque converter" so it looks like I'm dealing with a "so far" unmolested unit.
I'll pull the carb and let it take a Berrymans bath and give it a good scrubbing, beyond that...change gear ratio and lose a little top end? When I was able to get it wide open, it was certainly no speed demon, but I'm ok with that.

 

[Doc Sprocket]

I apogize, I misunderstood. I thought you had a centrifugal clutch.

That said, make sure everthing is moving freely, and the belt is good. Failing that, look for a stickied thread on torque convertor maintenance by Blazkowiez.

check/replace the spark plug while you're messin' with it

It still sounds like it may be carb related to me. Maybe take it off and give it another clean. Make sure all the jets are clear by using piano wire or some other wire to push through the jets. Sometimes you think the carb is clean but it isn't. It has happened to me before.

Thanks all, will be pulling the carb tonight, it'll get an overnight soak. I have a had habit of buying older lawn tractors that have been sitting forever, so carb cleaning is no secret, I think I have 2-3 gallons of Berrymans at any given time to soak things in. Hopefully that's all it is. This thing is def a big step up from the karts when I was a kid, having more than one drive wheel is going to take some getting used to, in a good way!

Don't forget to poke out all the jets to make sure they are open. An air compressor also works pretty well for this type of thing.

Let us know what happens...

From my experience with my road bike engine (I realize its different but maybe similar problem)
When it will rev fine in idle or with back raised but just has no power to push anything it is a fuel mixture related problem.
Mine was doing exactly the same things
Maybe this is your problem i'm not saying it is as my engine is a 250cc 4 cyl so there will definitely be some differences but maybe a thing to check.

wow...your's looks to be in a lot nicer shape than mine. i just picked up the same model kart...same paint color/scheme/motor and everything....but i bet my price "may" have been better than yours...unless you got yours for free.

anyhow..let us know about that carb. i just got mine running, but it needs some work. managed to hop around in the yard to let the 7 y/o have some fun in it before i tear it apart and rebuild it. mine needs A LOT of work.

 

[bcrewcaptain]

Whelp, everyone that had guessed the carb was right. After taking that thing apart endless times, cleaning, adjusting the bowl spring, letting the bowl ring dry out so it would fit back in, adjusting this, adjusting that, I finally figured it out. Somehow or the other I had overlooked the fact it was missing the main jet/pickup tube. It was by lucky sucking up enough fuel to run without it, not sure how. $1.47 later, she runs like a champ. According to my GPS, 23mph even with me on it(220lbs). The 2yr old is loving it, so it was worth the time and effort. I will load up some more vids, this is the only one I have right now. Thanks for all the help folks.

/unrelated, how are those tires treating you? I have this carts older brother with an 8 hp and less sheet metal, but it has some tractor style knobs on it and I was wondering if those were better.
