Apologies... carbs.
Hmm, rebuilt engine? Did you readjust the settings on the carbs? They'd need a new set up if that engine is running better. Only other thing is the vacuum advance on the dizzy?The engine has just been striped and rebuilt. Maybe 300 miles. I topped up the dash pots today and went for a short drive. Same issue. Maybe, just maybe, slightly less.
Good luck, let us know how it goesRight, thanks guys. A tune up was on my list of things to do.
The vacuum hose is new, but I will double check.
I would make sure the linkage is free and works well over the full movement. I've had a situation where it can go too far (over centre). I suggest that you use more throttle when driving than when it's got no load (stationary). Is the return spring good? Carpet/soundproofing clear?
Will do!Good luck, let us know how it goes
New springs. The only one I haven't checked yet is the spring on the pedal.I had the same thing with my 280z - turned out to be the return spring. It fell apart in my fingers when I eventually removed it.
