I have a 1993 Merc 4.3LX with full closed system. I recently purchased the Edelbrock aluminum Performer 2111 intake manifold for my Webber 4brl. The new mani doesnt have the mounting platform for the Webber carbs non electric choke. I dont want to have to buy a new carb if I dont have to, what can I do???<br /> Thank You!!
