Actually that's probably correct.
I had a problem years and years ago with the automatic choke on a Ford Escort.
It kept staying on too long and flooding the engine which then stalled.
I could tell it when it was going to happen and if you lifted your foot off the accelerator during that period (which only lasted about 30 seconds) the engine would stall.
Worse still if it did stall, when you tried to restart it the automatic choke came on and continued to flood the engine so it wouldn't start.
Anyway it was a known design flaw with that particular car and I was therefore able to find a ready made kit that would convert it to a manual choke.
All you had to do was replace the top half with a new one and fit the manual control to the dashboard.
My brother and I went to take off the old one and discovered it was fitted with security screws.
We had to borrow security bits to get the screws out yet the replacement fits on with normal screws that use the same holes. So in other words there was absolutely no need for the security screws other than to prevent people from working on it. :rolleyes:
