xdfairmont79 135 Posted October 7, 2014 so, ive been fucking around with my xf and changed the carby, still a stock 34adm, but. i noticed that the throttle return spring at full collapse, is still only 3/4 or so throttle......... yanked that prick out, put a return spring from the inlet mani bolt to the carby and bam, it actually moves now. try it and see if it also works for you!!! cheers. 5 dizzy616, XTREME KARTS XF, XFChris and 2 others reacted to this Share this post Link to post Share on other sites
SatansReverence 264 Posted October 13, 2014 Never had that problem but I've seen XF 34 adms that have a notch in the throttle lever that prevent the secondary from opening all the way. 1 deankxf reacted to this Share this post Link to post Share on other sites
