It is missing quit a bit of stuff and was trying to bring it back to life. I bought a predator 99cc engine from harbor freight hoping it will work but after taking the centrifugal sprocket clutch off the trashed Tecumseh engine the shaft bores are different. So my question is can I get This

and all my problems will be cured or is there a lot more I'll need? I will take pics in hopes that will help. Update later. Thanks ahead of time.

Question 1. What made you get the 99cc engine?
Question 2. What size is the tecumseh engine?
Question 3. What size bore is the clutch from the tecumseh engine?

Pics will definitely help; a picture tells a thousand words

If that is a small kart, 99cc is OK, but I agree with Fabroman, why the 99cc?
The clutch in the link will work on that engine but make sure you get the chain size correct.

Ok went with the 99cc do to cost.
Not sure what size the tecumseh engine was.
The tecumseh is a 3/4 and the predator is 5/8.

cost. Ok, how do I know the chain size. I found a part .pdf file for this kart it says.

60t and #41 I can deduce that is 60 teeth but the 41 is where I am lost but in that link it says 40-41 so I am hoping that will work. (I am charging my camera so I will post pics in the coming hours. Thanks)

Thanks for replies!

oops sorry forgot to resize.

Fixed

Ok, you've gone from a 5hp down to a 3.5hp &, to make it worse, you could've gone up to a 6.5hp for the same money

or am I missing something...

My advice is, if you haven't started/filled the engine yet, take it back & upsize to the 6.5hp & all your problems will be solved; you won't have to buy a new clutch & you'll have nearly twice as much power. If you have filled it, drain it & take it back anyway, you never know your luck.

 

[qtband]

I agree. The 3.5 will work, but you soon won't be happy. Whenever you order a clutch, you have to match the clutch to your chain size. So a 41 chain needs a clutch that has a 41 sprocket.

I'd like to point out at this moment that the 97-99cc engine sold by Harbor Freight doesn't even actually have a 5/8" shaft. Its a hair bigger, people over and over have to shave them down. Past that the linkage is far more difficult to hook up than the 6.5hp.

 

[crmzendrgone]

Ok so I went and got this http://www.harborfreight.com/engines-generators/gas-engines/212-cc-ohv-horizontal-shaft-gas-engine-certified-for-all-states-except-california-69730.html engine. the clutch fit good. Couple more questions:

1. Does the key way need to be in place? if so then the clutch will not fit over the shaft with the key way inplace.
2. I think the axle shaft (if you will) is bent cause the chain doesn't seem to line up quite right. ( I have not buttoned anything down yet though so)
3. Where is there a good place to get parts for go karts? The bearing for the wheel hub(?) are bad, plus I need a lot more parts, tires, throttle cable, etc.

Again thanks! for all the input.

 

[crmzendrgone]

All take some more pic. when I get a chance.

 

[OzFab]

Ah, that's better

1. Yes, the key stock needs to be in place, otherwise your clutch won't operate. Try the key in the output shaft, then in the clutch; turn it to make sure all sides fit. If it fits in both, it should fit in both together.

Once you've made sure you have the correct size, try fitting the key after the clutch (if possible)

2. The output shaft must be exactly paraller to your axle otherwise you will get that twist effect.

3. Ask anderkart, he's in Phoenix

 

[anderkart]

word is your here in Phoenix? I was wondering where there is a place that sales go kart parts. I started a link here asking questions and need some assistance.
Thanks!!

Ok I took some pictures of why I believe the axle shaft is bent on the frame. (Pic 1-3)

this last one is to show that I have the bolts in so it is more inline where the slots in the plate are.

 

[crmzendrgone]

Oh I'll have to take a pic of the shaft and get some input on the key way situation. Thanks.

 

[OzFab]

The only way to tell for sure if it's bent is to take the hub off, get out your set square & start measuring...

 

[crmzendrgone]

silly question but what should the measurements be

 

[crmzendrgone]

AM I comparing it to the other side?

 

[OzFab]

silly question but what should the measurements be

How long is a piece of string? It depends what you measure & where.

AM I comparing it to the other side?

That's probably the best way, however, If the other side is also bent, you won't get a true reading.

Here's a simple trick: Set the base of your square along the frame adjacent to the axle. Use a ruler to measure from the axle to the square. As 99.9% of axles are set @ 90* to the frame, the measurements at both ends of the axle should be the same.

To measure for vertical bends, lay a straight edge across the frame (from one side to the other so it's touching both sides). Again, measure from the straight edge to the axle at both ends.

So i just picked up one of these karts and mine looks bent also. Still seems to work ok, just worried the chain will come off.

Might just convert to live axle setup anyways......
