hello, ive just picked up a ryobi 31cc from a weed trimmer, and am using it for conversion. i have heard the stock carb is restrictive so am thinking of the WT-499 carb, right in my price range for $35.my assumption is i would need no other mods to the carb as it is for alky. has anyone done this before? i cannot find if it is a pump style carb or not. would this be a resonable start?

thanks in advance
