That wasn't much fun - I was just coming home from work, heading out of London on the A40.
I was "making progress" as they say, shut the throttle to avoid plowing into the Datsun doing 45mph in the outside lane, and she just kept accelerating.
Good thing there were no plod around, I had to swerve to the inside lane and just keep going through the Hanger Lane underpass, brakes on and still accelerating.
Came out of the underpass, hit the kill switch and headed for the side of the road...
I had a poke around to ensure the cable hasn't fouled, doesn't seem to be. After opening and shutting the throttle a few times, started her up, and now the throttle seems to be jammed around a quarter open. Managed to ride the rest of the way home like that, not far fortunately. Got a few odd looks sitting at junctions with the engine idling at 4000 rpm.
Sooo... tomorrow, I'll have to investigate. I've been having problems for a few weeks with what feels like a fuel starvation problem at speed. Anything over legal speeds for more than a minute or so, and she starts to bog down. Slow down, and she picks up again. I'm thinking perished rubber diaphragm in the carbs for that one. Don't see how that could cause the throttle to stick though.
