Default Clutch engagement on deceleration??

I have my buggy setup. The last item I want to address is the clutch.

Should the clutch stil be engauged when the motor is off throtle? I can hear the motor decelerating when the throtle is closed.

So the clutch is hanging on decl. Is that good? Is the clutch setup wrong? What should I do to correct it?

Thank you

Either your idle screw or bottom end needle or both are set too lean.

What type of clutch shoes and springs are you using?


There will be a certain amount of clutch engagement during de-celeration....until the rpms get down enough for the srings to fully close.

If it engaged while setting on the box...it may be your idle...or low end settings as described by someone else.


It may also do that with too light of a clutch spring.

NO. When the buggy is coming down the street. When I let off the gas you can hear the motor slowing down at the same speed as the buggy.

So the clutch is not disengauging. Same as a Manual 1:1 car when you DONT push the clutch in. The motor is acting like the brakes of the car.

Should the clutch disengauge when the throtle is lifted? so the buggy can roll through the corrners.

The clutch will stay engaged during de-celeration until the engine rpm comes down enough for the springs to relax back to neutral...similar to a real car braking thru the engine. It will not go to neutral as soon as you lift from the throttle. If you have a broken spring, or you clutch and springs are not installed properly, the car will usually have alot of drag on it during de-celeration...and sometimes stalls or sounds as if it is fixing to stall. And may seem to not accelerate well...like the the tune on the bottom end is way off.

As long as your idle isn't obviously too high on the box... and your clutch setup is installed correctly..everything should operating normally.

Talking

clutches are centrifugal and at a certain rpm , depending on springs , clutch shoe weight and a few other minor variables they engage and disengage in the same rpm range . so think about what the rpm is when your clutch engages and this should be approximately the same rpm that it disengages also another tuning tool for the track
happy running ,
monty



if it stalls at idle there is a problem
if you maintain your clutch properly and often , it will run the way it was designed to , as it is a key element of the car

Check your CB, it may be wore out and the groves are holding you shoes

Check to see if the shoes are mushroomed, it will make them hang. If they are and your shoes still have life in t hem just file them down.

Might want to consider posting some close up pics of the clutch. That will enable people to see exactly what the problem may be.
