Adjust carburetor slide on 04 660 rhino

my rhino with JBS sheave &orange spring will only top out at 45 MPH..talked to James and checked  a few things and it looks like my carb slide isn,t opening up all the way ..so no top end..searched on here & you tube but didn,t find anything for the 660..so need help,lol..Danny

not sure if they can be adjusted as its a vacuum slide have u pulled it out an cleaned it and the carb where it slides. I know they will get dirty an stick I clean mine with some wd-40 an wipe it down good.

have you check the throttle cable adjustment may not let you open the butterfly wide open if its not adjusted correct

good point, ive heard the throttle cables stretch over time on the rhinos not sure if its true but worth a look

mine did , an dam what a difference 

.will check that out on the throttle cable stretching..will try to find a break down of the  carburetor assembly and clean it up or replace the vacum diaphragm..it never has really been fast..but when I first got it had it rejeted for running in the mtns and just has allways been a dog..again thanks guys for all the suggestions..Danny

have you looked at the plug see what color it is , better than that get /borrow a a/f gauge  make sure the jetting is correct , if its always been a dog may have been set-up wrong back then

well checked a few more things..throttle cable opens carb butter- fly all the way open..valve lash good..other than the top speed runs much better..any more suggestions ? Danny
