i found the right carb for my 85' Jag 440, but at idle the motor still seems very bogginy. i played with the jets and it didn't help. since it is oil injected i can adjust how much oil is mixed. the only problem is that i can't find out what the ratio would be at a certain point on the cable. I would just ditch the oil injection but i heard bad things about doing this on the jags. can someone help?
