Choke valve jiggling needed to start the car
Posted: Wed Sep 30, 2020 5:39 pm
I bought a Capri recently, it has a single venturi carb on it
It worked very well when I bought it, started up on a dime every time, no problems
But slowly over the last few months its become hard to start, cranks but doesn't actually start, this is issue is worse when cold
What does help it run every time, is whilst the starter is turning, to manually jiggle the choke valve on the carb. The engine does start then. This makes me think it's just the air/fuel ratio getting upset here.
How would you go about fixing this? I'm assuming this requires some tuning to the carb, which i'm assuming you can do with just the screw?
But why would the carb slowly become more and more 'uncalibrated' over a few months. Is there another issue I should be looking out for?
Thanks
