centrifugal clutch Smoking

[bda28590]

Its a Brand New Clutch 12 teeth and the Sprocket is 54 teeth or 50 something and the tires are from a rideing lawn mower 12" maybe 15" and im useing a 6.5hp 3600RPM Max And if i ride it for like 10 sec. it starts smokeing really bad every thing is new what would the prob be? How can i fix it? also im useing a #35 Chain

your gear ratio is incorrect. You need atleast a 6:1 ratio. Meaning you need atleast 60-70 teeth on your rear gear.

My clutch never gets so hot that I can't touch or hold it with my bare hands.

 

[bda28590]

i think i might need to put smaller tires on it maybe that will fix it

 

[Russ2251]

I run 11.5 diameter slicks with 72 tooth driven sprocket along with 17 tooth heavy duty Noram centrifugal clutch.
This makes my final drive ratio 4.24:1.
I would rather have an 11 or 12 tooth clutch but none are available for my application.

Cant run a gear that tall without a CVT.

some one told me today to make a clutch stop slipping to take it a apart and stretch the springs a little will that work'?

 

[Russ2251]

Bad idea. Clutches are to be used as-is straight out of the box.
If it doesn't work to your satifaction then something else is wrong, be it incorrect ratios or some other overloading.

i didnt think it would work or mess it up, it was a guy that worked at Tractor Supply Company that told me i could do that probally was hopeing i would do it and mess it up so i would have to buy a new one lol

i have seen this where there is a centrifugal clutch belt driven on another pully chain driven does that help the clutch out? and what is the best ratio if have 15" tires lawn tractor tires or sould i just stay with the centrifugal clutch direct chain driven? sorry im still new to this...

got another question i go around the house and the engine shuts off on me full tank of gas im woundering because there is a safety cut off for low oil but there is oil in it up to level can they some time go bad on you even if its a new motor or would it be something else? i don think it would have to do with gas but if it did i used Premium Gasoline thats the only thing that gas station had it the time due to the shortage of fuel

Its the low oil sensor cutting out your motor.

 

[Kenny_McCormic]

Unhook the low oil sensor.

 

[bda28590]

That fixed it, Go figure its a brand new motor maybe the oil splashing around makeing the sensor think there is low oil? who knows

 

[Kenny_McCormic]

yep

Just remove the whole darn thing when you go in for a rebuild.

 

[jr dragster T]

I agree with Oscar. Remove the entire unit from the bottom of the block.

You'll need to add about 2oz (IIRC) more oil then.
