Wheelhorse84 87 #1 Posted December 2, 2012 I just bought an older style carter carb for my c-160. It idles really well but once you get to halfway it sputters coughs and wont go to high idle or even stay on medium throttle. I tried adjusting the main needle screw but no diff. Any tips. thanks By the way The carb is completely rebuilt and cleaned. Share this post Link to post Share on other sites
rmaynard 16,348 #2 Posted December 2, 2012 Who rebuilt the carb? If the main needle valve is not cleaned inside of the tube, you will have rough running. Also, is there any slop in the throttle shaft? Was a new bushing installed when the carb was rebuilt? A carb that is just cleaned and has a "rebuild" kit installed is not really rebuilt. There is a bit more to it than just replacing the float valve and bowl gasket. 1 Share this post Link to post Share on other sites
Wheelhorse84 87 #3 Posted December 2, 2012 I bought 2 of them and i just put the second one on and it runs great. Both have new throttle bushings. Share this post Link to post Share on other sites
