King throttle control

reading some of the recent posts about this. Just looked at specifications of my coach and they just indicate cruise control. Trying to learn before break down along some highway....(travel getting closer, just spoke to Coach Net to see how much to save up for coverage). Then I read about broken throttle return springs and runaway RPM's and things of that nature!!
Thanks much,

I wouldn't stress to much about the throttle return springs thing. When we bought our coach I thought that the throttle was very touchy at low rpm ,idling and city driving. Come to find out ,when I was starring at the 8.3 that both springs were disconnected. I reconnected them and imediatly noticed more resistance in the throttle. But it had not been a " run away " throttle before.  AND they disconnected once more after a few thousand miles, so I bent the ends just a little different and problem solved, but I keep an eye on it now.

We found that our throttle springs are made of harder material than the steel they were attached to.  Looking closely I saw that the spring was cutting a groove in the bottom fixed attachment point and the top rotating assembly.  Probably happens from years of rubbing one point inside the small holes the springs are looped through.  In time the groove could wear through completely. 

We carry spare throttle return springs that we made from Lowes/hardware store springs that seemed to have the same pull resistance and wire size.  But we did have to shorten the new springs by cutting it shorter and with a pair of long-nose plyers make a new end loop.

Here are a few old links about making new throttle return springs, their importance, and how we made a modification that handles the spring cutting through the metal.
