I got an 8hp briggs with a 1 inch shaft, and the only clutch i can find is a 14t. i am using a stock yerf dog 3202 if im correct 60t sprocket. will it still be torquey and fast?

No

And you also haven't given us enough info to be 100% sure.

14t clutch 8hp and a 60t sprocket will it be good or what. im asking because im not an expert on gearing. if not my grandpa might have a friend who has a way to machine it to a 3/4 inch shaft so i can fit the correct clutch.

We need the tire diameter, estimated weight, expected use, blablabla...
It shouldn't be too hard to find a 1" clutch online....
But if this is going on the Yerf Doge with off roading, probably noooo, 4.3/1 is way too high.

You might be able to get away with a 1" bore 30 series.

NO YOU DON'T! You can get a different clutch!!
https://www.gopowersports.com/10t-1-...gal-clutch-41/
Yes it is $80 but it will save you a lot of grief turning the crank down and making a new keyway.
P.S - I watched your video, and i highly doubt that is a 50s or 60s engine, it looks way too new with the plastic dipstick cap.
Also, I don't think Briggs EVER had the year on the dipstick.
Send me ALL 3 of the numbers and I will decode them for you.
The number you read off in the video(1964) was probably the model(first number), and NOT THE YEAR.
Please send me the numbers.

EDIT - I am you two posted while I was writing LOL, but a clutch is cheaper.

Here is a reduced bore clutch 10t-#40/41. Obviously outboard only...
Im thinking youll be better with a jack shaft when running a larger bore like this... itll be way easier to modify ratios aswell...

The GPS one is the cheapest CC(that I know of), so you should probably just get that one, 'cause then ya don't have to worry about turning the crank down or anything.
Also, if it turns out to be a bum engine, you can just save the clutch for another project.

1.5 hp probably won't destroy it. (disclaimer: probably)
And even if you get the front pulley and use your rear one, you still get to align it and get a belt.
I say CC.

The TC that I linked is still cheaper than the clutch from gps. And will drastically improve the acceleration of the kart.

Again though, he gets to align it, figure out a jackshaft/backplate, and get a belt. And if he does a jackshaft he gets to align it.
Considering the tedium of aligning it and getting a $10-20 belt, and he already has to rebuild the driven if it can be salvaged, it'll be about the same price if not more expensive than the GPS CC, and harder at that.
But if Trevor wants to, it will give better acceleration.

Oops, just realized that's a full kit.
In that case, TC!

I will once again say no it won't work with that gearing. And I will once again ask what other info you can give us like tyre diameter. If you told us already, I apologise.
