Hi,
I have just bought a 2L cc and have been experiencing a grinding kinda noise when slowing down in 2nd gear when the clutch is in. The clutch is fine going up the gears it just occurs when i drop into second or first:scratch:
i would be grateful of any advice or possible cause.
Thank you:)

My only suggestion, other than clutch drag, would be worn synchromesh on 1st and 2nd gears.
Sounds as if they've had a hammering from an unsympathetic driver in the past.
Take your time when changing down. You maywell find that double declutching helps, but not many people remember how to do it properly. People of my age do, because we were brought up in an age of non-synchromesh gearboxes.
Modern cars have a type of gearbox called 'synchromesh', which allows you to change smoothly between gears. You can even 'skip a gear', for example changing down from 5th to 3rd without any negative side effects on the gearbox, although the situations in which you might need to do so are fairly limited.
Really old cars, from the 1970s or older, were not fitted with synchromesh or only had it between 2nd and 3rd gear, which meant there was much more of an art to changing gear. To prevent clashing of gears during changes with damage to the gearbox, a technique called double declutching1 was used.
In ordinary declutching you use the clutch to change from a higher to a lower gear. It's what you do all the time. Double declutching is a little more elaborate:
* Push the clutch to the floor
* Put the gear lever into neutral
* Lift the clutch off the floor
* Give the accelerator a little blip to rev the engine up
* Push the clutch to the floor
* Put the gear lever into the desired gear
* Lift the clutch off the floor
Why do it? It puts the gearbox into an intermediate state where it is better able to slip into the new gear, and matches the engine speed to the new speed required by the lower gear.
The same process in reverse, but without the extra blip of the accelerator, is used to go up to a higher gear.
