Throttle not returning to idle?
Throttle not returning to idle?
I noticed yesterday on the run back from Stanford Hall that my throttle would not return to idle when releasing the accelerator. This actually proved a nice form of cruise control on the way through the m6 average speed sections as it sat quite nicely at 50 in fourth.
I'm going out today to clean and grease my pedal assembly etc, and oil my carb linkage. I check the cable was moving freely upon returning home and removed my mat at a services on the journey in case this was the culprit.
If none of the above work I was thinking it could maybe be my return springs weakening? Or maybe carb inlet gaskets, as it only seems to happen after a motorway run?

Re: Throttle not returning to idle?
Maybe the warmth of a run dries out the old grease on the cable? WD40 squirted down the conduit, maybe?

Re: Throttle not returning to idle?
I'll give it a try. I've currently got the fpotwells stripped down looking at the pedal assembly, it appears to be missing a circlip securing the arm for the throttle cable to the pedal shaft, so I'll get one of those as it was allowing the shaft sideways play which could contribute? The cable promptly fell off but luckily it didn't disappear into the tunnel!Editor wrote:Maybe the warmth of a run dries out the old grease on the cable? WD40 squirted down the conduit, maybe?
Re: Throttle not returning to idle?
Certainly could have been the main problem. Any part of the shaft not being rubbed would have surface oxidation, so it it moved a bit, it could bind slightly.

Re: Throttle not returning to idle?
I've ordered the missing items along with a spare throttle cable(I'm currently without), I'll report back once all is assembled as it should be.
Re: Throttle not returning to idle?
I had something very similar on the way back from Ninove. It turned out to be the carb linkage rod locking nuts weren't tight and while one of the rods got longer it held the other carbs throttle off the stop.
Worth checking anyway...

I'm glad other people have experienced that.... very embarrassing when it happens in a town centre
Re: Throttle not returning to idle?
Still working on this btw, have the circlip now just need another pair of hands to reconnect the accelerator cable. I have managed to squirt wd40 into the tube though, feels like it's moving smoother already.
