4K Carbi

[Heath.]

I have just rebuilt my 4k carbi just so it finally runs ok. BUT it isnt returning at idle? everything seems to be right on the carbi itself so it has left us stumped... :glare:

any help would be great.

Do you have the "slow return dampener diaphram" working on it?? The thing at the front that catches the throttle and lets it down slowly..

I took the bolt out & reversed it so it didn't catch the throttle and it sat at idle better.

 

if you take the cable off, does it make a difference?

 

If you take the return spring off, does it sit back to idle freely & easily?? If you have had the throttle plate out you can get the throttle shaft binding just as it closes, which makes it hard to close the last bit.

 

Can you slow the idle down to stalling point? Do you need to push the shaft around to make it slow right down??

 

..and does altering the mixture screw do anything?
