I tend to think that both TB's should open at the same time if things are working to plan....is that right??...it frequently starts running rough at low end so i need to constantly rebalance them, i am begining to think that the right throttle stop has been fiddled with...the TPS reads 0.365v as it should but tickover is about 1500 and the BBS are only out approx 3/4 on one and 1/2 on t'other...
i have just checked the valves with 2 feeler gauges and set the end float of the rockers at the min needed.........i'm going dotty over this...............
