Todd 2 #1 Posted November 10, 2012 the only problem in having with the 520 is while running and working is that the throttle keeps falling down so i have to keep moving it up to keep the power up.There is no oil or grease on the pinion to the cable.Any low cost ideas on how to fix it ? Cut out a peice of hard rubber and drill a slot over the throttle bar to pin it up against the plate so it wont fall ?Any ideas ? 1 Share this post Link to post Share on other sites
wallfish 15,770 #2 Posted November 10, 2012 I'm not familiar with the 520 throttle but there has to be a screw or a rivet at the pivot point of it. I think it's a rivet so you could brace it on a vice or something and tap it with a hammer until it tightens up to create enough resistance to hold it in position, Share this post Link to post Share on other sites
Foozerush 40 #3 Posted November 10, 2012 Squeeze the rivit with vice grips.... Did mine on my 416-8.... Super easy fix. Share this post Link to post Share on other sites
P3x 53 #4 Posted November 11, 2012 Had the exact same problem with my '93 520. There is a rivet that attaches the throttle lever to the "quadrant" forward of the instrument panel. I tried to tighten it using the vice grips method and was unsucessful. Used a pneumatic rivet gun/muffler tool to tap on one side while backing up the other with a bucking bar and lightly drive the rivet to tighten. Been fine ever since.

I think it's a rivet so you could brace it on a vice or something and tap it with a hammer until it tightens up to create enough resistance to hold it in position, I ditched the rubber over the handle idea.took some channel locks and squeezed the pinion on the cable ,works like new now.I guess different methods would work,all depends on what condition peoples cables are in ..Luckiley mine just need a good squeeze ..
