My throttle doesnt really creap, it pretty much falls all the way back to idle once i get up over 1000 RPMs. Right now i just stick a half of a cloths pin on the red handle when im cruising to keep the RPMs up, but im adding control to my tower in the spring and dont want to worry about having a cloths pin in the throttle im not using. This only happens when the engine is running too, when its off the throttle doesnt pull back. I am thinking about putting a spring down on the throttle linkage to counteract whatever is pulling the throttle back. Its an Isuzu 226 6BG-1T engine. Anyone ever experience this before or have a better fix?
What kind of controls do you have?The injection pump should have a spring that assist the application of throttle.Some have a tension adjust on the spring.If you have Kobelts ,tighten up the allen screw inside to adjust the plastic puck that holds tension.If you have morse,tighten the allen screw inside the control handle.Back in the Detroit days,before Kobelts,we used to take the set screws out of the morse controls,and put a hex bolt in its place,so you could easily adjust it.A dexter russel knife could be found on many lobster boats jammed in the throttle.
Yeah chances are your adjustments just need some tweaking for the friction on your throttle, my own throttle rockets back as well, but I prefer that option. For when 6 year olds standing on a pail grab the throttle, fun times fun times. Also for when I have charters on board, gives me peace of mind.
