Problem is I dont think the carb is working correctly either, when the throttle is opened fully the two butterflies are not opening much. The car does not have that much power for an XR2, I have just bought the car and I think someone has been working on the carb, there was a bit missing off the choke, the small bar that increases the revs when cold. I got the part but does not improve things. Think it may be better fitting new one, any thoughts folks??
