chain help

[bmx xxx]

hi, i have a oddy 10 tooth rear hub rhd, with a 28 tooth sprocket,
i have changed the chain twice both different chians,
when i pedal i get this noise, like the chain is rubbing on metal, or the chain has to much play in the tooths,
ive tried moving the back wheel in and out as to give the chain more or less play, but still the same
do i need a half link chain
one of the chains was a kmc the other was a izumi, but not half links,
hepl this is driving me crazy
cheers in advance gary

I've got the same 28/10 set up.You dont need a half link. Make sure the sprockets line up as you look from the rear of the bike.If the cain is too tight it will also make a noise. Hope that helps.
