I’m still getting to know my new XK140 and really enjoying it. When I first got it the turn signal was self canceling after about 20 seconds, which I thought was quite cool for a 1950’s car. The last few days it cancels after just one “Blink”. If I hold it it keeps blinking, but I actually feel pressure on the switch wanting to return it to neutral. I’m not sure what changed,iIs there some kind of adjustment for this? I searched the forums and didn’t really find anything.
There is a screw that is supposed to adjust the amount of air bleed. It’s possible that has worked loose but much more likely the leather washer has either dried out or cracked.
If you’re not sure what’s inside the timer check my post 6th November 2017 for a photo of the innards.
