I had a cns carb on my 48 cc which ran good for a year then I got a bad miss and I pulled the carb off the intake and put it on a couple times to see the float and the jets.Now the spacer is wore out,so I bought a nt carb and it runs good but it vibrates more now than the cns.So wanting to know is there anything I can do to get it not to vibrate so much.
