Im stumped. I have a 92 jag 440 that ran fine last year when put up. Started right up and drove off trailer this fall for maintenance. Took carb off and cleaned. Put back together and it will only run if i disconnect choke cable completely. That maybe I missed some dirt somewhere so did it again. Same thing. Whith choke cable unscrewed from carb completely shes purrs like a kitten. As soon as i drop plunger in hole and start to screw in it will die. Any thoughts?
