    cogs worn? chain worn?

    It just sounds like the low extent screw needs tweaking a bit, probably that it cant get onto that cog enough making it half jump up when pedalling?

    that sound right i had a really close look and noticed the chain was not making contact with the bottom jocky wheel it only occasionally dose this what should i do to shift it about 1mm across. could my dropout be slightly bent still. thanks.

    replace drop out then, or straighten it. Even though you say you have. Or is it just a stiff link?
