Radioactive Man Posted July 12, 2021 Share Posted July 12, 2021 There is always something isn't there? Since the car is back from paint repairs went for a run yesterday and when cold the accelerator pedal is nice and smooth, easy to press. As the car gets hotter then the pedal becomes stiffer and feels really notchy and not easy to modulate. I cant see anything obvious, the cable feels free and not binding if I disconnect the cable from the throttle linkage. Is it possible that something on the carbs is binding due to getting hot? I cant see anything obvious but the pedal feel is changing to the point its not pleasant to drive when hot. Thanks in anticipation for any good ideas.

That area gets pretty toasty. I’d be looking at the quadrant where the cable attaches and the link rod down to the throttle link shaft. Also check that the link rod has a bit of free-moving end-float even when warm. 1 Link to comment Share on other sites More sharing options...
Sprint95m Posted July 12, 2021 Share Posted July 12, 2021 A general observation, if I may…… Many years ago I was told the first thing to check for in such a circumstance is a poor engine earth. (If the earth is really bad the car will struggle to start) Ian 1 Link to comment Share on other sites More sharing options...

And then try disconnecting various bits to see if you can isolate where the stickiness goes away. Starting at the pedal itself.. I assume it all frees off again when it's cooled down? 1 Link to comment Share on other sites More sharing options...
Radioactive Man Posted July 12, 2021 Author Share Posted July 12, 2021 Thanks as always. Just in from work so will have a look tomorrow night as hopefully home at a sensible hour. Sounds like a few places to look. Ian Link to comment Share on other sites More sharing options...

rogerguzzi Posted July 24, 2021 Share Posted July 24, 2021 Hello Ian It was nice to have a chat and we will get it sorted bit by bit but we have to get rid of those wax stats and valves in throttle plates. Then think about cams etc Roger Link to comment Share on other sites More sharing options...
