I have completed the major service of my 308GT4. Now, when accelerating at lower revs, it pulls fine with little throttle, but with more throttle it starts to spit and hesitate, before it starts to pull. This is really bad at about 2000 revs, gets better with higher revs. From 4000 there is no hesitation even at full throttle. There is also a lot of popping from the exhaust at deceleration.
Jets are cleaned, accelerator pumps are fine and working.
I had the cams reground at Webcam. Slightly longer duration and higher lift and less overlap (Webcam's 308 performance street specification). Everything else is stock.
Another thing is that the car did not run for more than a year, did about 400 miles since.
Any ideas? Do the carbs need re-jetting due to the other cams?
Best regards
