Review on High-Quality Carburetor for Honda ATVs: Compatible with ATC250SX & Big Red ATC250ES (1985-1987) Including Throttle Cable by Olajuwon Achille

Seriously don't buy this for the SX unless you have experience. I forgot to read the reviews before ordering but it doesn't fit in anything other than shoe size to the SX. I had to trim the frame to make room for the top of the carb, as well as fully adjust the throttle cable, and I had to re-wrap it around the throttle. The throttle body assembly was wrong so I used old parts. After a 2 hour test of what should have been 20 minutes, it works, but it's nowhere near in stock.
