I just check it out for you (I was wondering if they raised the prices on the 100/125 glows too),, see my link, the 21's Carburetor is unavailable, they must have changed the Carb,

that's a big jump in price just for a Carb, I wonder if they are going to pull it off their line up so they just raised the price ?? you never know
