hey everyone, ive decided to go ahead and attemp to jet carbs on my own for the first time. i got a #130 main jet on the way and a #38 pilot jet coming and some shims for the needle. what i need to know is, is there any special tools to remove the jets or needle? the jets look like they have a slot on them but that might not mean its ment for a screw driver. i dont want to destroy anything and not know i did damage. any other help or tips would be greatly appreciated about needle shimming. thanks a bunch.
