Default Why is this happening?

Hey guys, today when i started my v spec on my box i noticed something strange. Actually i dont know if its normal or if something is wrong. When i gave my engine throttle while the buggy was still on the starter box, the wheels continuously spun very fast. And there was a noise to it as well. Im not sure if maybe i didnt tighten the clutch bell onto the crankshaft right enough or what. Here is an example of what my buggy is not doing:

When this person gives their engine throttle, they slowly come to a stop. But mine continue to spin. Any ideas?

See how he gets the speed up but the tires eventually slow down, thats definitely not what my buggy does.

Well it could be your bottom end is fat. If your just saying the idle wont drop right away. The wining noise could be bad bearing in the clutch. If you don't have it anymore I wouldn't worry about it.

It was also doing it at leisure hours. When i came down the straight and let off the throttle going into the first turn it made the whining noise. So should i get new clutch bearings or since i got the new engine it will be fine?

I would change the bearings, they are only a buck for one. I change the bearings every weekend. I also race twice a week though. Also put a rubber band around the carb so it closes when you get off the throttle. I have seen some guys were it hangs open just a little. Then it close when the brake is used.

am i the only one who has a problem with the fact that your asking a question about a motor you don't have any more?

and your problem sounds clutch related. weak clutch springs can cause your clutch shoes to grab at idle speeds. also your idle gap could be too big and that would cause your engine to idle too fast

Why is there a problem that i dont have the engine anymore? Its still going to happen if its the clutch not the engine. Thats what you just said to fix so i dont get why you came in here saying there is a problem?

Few things come to mind:
Will the engine idle at all without the wheels spinning?
When off, will the clutch bell spin without moving the flywheel? (If the flywheel spins either your clutch bearings are gone or your clutch nut backed off.)
If it's tune related, try to lean your bottom end about 6 hours and lower the idle about 5-6 hours. It's very common for people to have a very rich bottom end and have the idle high to compensate. When this is happening then when you let off the gas it will stay 'up on pipe' and have a 'run-on' feel to it.
Hope something here helps ya!
