bo dawg 516 #1 Posted May 25, 2022 I believe I have the cheaper later carb on this. Just trying to clean from the top without un mounting it. What is the plastic thing on the side of it? Share this post Link to post Share on other sites
lynnmor 7,307 #2 Posted May 25, 2022 (edited) The plastic thing is on most carburetors for the past half century, they are there to limit adjustment of the idle mixture screw(s). Most people discard the junk. Edited May 25, 2022 by lynnmor 2 Share this post Link to post Share on other sites
bo dawg 516 #3 Posted May 25, 2022 My other 520 don’t have that but it is also the better carb to have. Share this post Link to post Share on other sites
