Besides not touching, is there a certain amount of space that is required between a centrifugal clutch and the rear sprocket. Will post pics if needed.

to the forum!! We need photo's; the more detailed, the better. Speaking for myself, the reason I became a machinist is because I flunked mind reading in school. I don't know about the rest of the forum on that point, but I DO KNOW that we love photo's. Lots and lots of detailed photo's!!! That's why our web host has gifted us with this emoticon;
Bring on the pics!!!

Hello fello Arky I read some where that its best to have them far enough apart to have at least haft of you small sprocket rapped with chain.

Hey Arkyhunter, I'm in Benton also. Here are a couple of pics. I'll take more in the daylight later.

The motor isn't mounted at this time, just sitting on it's plate. Let me know if you need additional pics

Easy to look at photo's!!! Thank you!! Thank you!!
Now, as a loose rule of thumb, Arkyhunter is correct; but, as we all know, things don't always work like that.
Now, there may be a "set in stone" rule for these things. my personal experience with chain drives is you need at least enough distance between drive and driven sprockets that any slack in the chain can't get "pinched" between the two. You also have to monitor the slack in the chain so that it doesn't try to "ride" the unloaded side of the system by rapping any slack around one of the sprockets, causing it to snap.
In a chain drive with only two sprockets, they both turn the same direction, regardless of speed. Where the danger comes in is that in the area where the two sprockets face each other, they are turning in opposing directions; thus creating the potential for bind up/snapping/real carnage.
Properly set up, you should never have that particular issue; you just need to be aware of it....

Well the closer the sprockets are the lesser the amount of chan on the clutch. As long as the chain is tight you should be fine.

Thanks for the help. I guess I could always, weld some 1 inch square tubing on the plate and raise the motor an inch. Do you think I would be better off to make that move.?
The chain cannot be too tight. A tight chain puts too much strain on all drive components and is never recomended. There MUST always be a certain amount of slack in the chain
In my opinion, this would be the best way to go. Your sprockets are way too close the how they are now.

The one pic you didn't post (side view) will answer my question: How far can you slide the engine forward? The farther forward you go, the farther away the sprockets get from eachother
Raising the engine will also raise the centre of gravity (negligably but, worth mentioning); try to avoid that option if possible...

What type go kart are you working on? How many teeth are on your rear sprocket.

It's a homemade cart. The centrifugal clutch is 10T and I bought a #35 chain. The chain will not work with the rear sprocket. I'm not sure of the tooth count, but it is more than 54. I ordered a 72T rear sprocket for a #35 chain last night. I'll post pics once, it is all completed.

Is the clutch #35? I didn't think you could get a #35 10t clutch...

When I ordered the chain it said it was for a 10T sprocket. My other go kart has a 10T sprocket with a 54T rear sprocket and a #35 chain. Hope it works?

Fabroman, what pitch chain would you pair up with a 10T sprocket?
It depends what pitch the 10T sprocket is. Unless you know the sprocket pitch, you cannot get the correct chain (unless you guess correctly)

Well, I guessed wrong. The chain fits the 10T clutch sprocket, but not the 72T rear axle sprocket. Ya'll have any ideas?

Define "doesn't fit": Is the chain too big for the sprocket or too small?
Measure the distance from one tooth to the next on the both the clutch sprocket & the axle sprocket & report back. Hint: It should be either 3/8" or 1/2" (or, maybe 5/8")

Chain is too big for 72T rear sprocket. Teeth too close. I will measure chain once I get a chance. Thanks
