ok carbi's been checked few things replaced runs real nice now. timing is set at 29 degress with vac advance hooked up and there is still a slight flat spot when u put ur foot into it. it doesnt ping either. any ideas on what is causing the flat spot mechanic cant work it out. could the cam be a tooth out when we put it in????
just wondering why it can be at 29 degress and not ping? could it be a fuel issue with the flat spot? as i only have the mechanical fuel pump in it (there no pumps inside or outside the tank anymore)
other then the flat spot it runs perfect. when ur into it after the flat spot goes it revs real nice but then bogs down a little towards the top rev range could this be fuel issue as its not getting enough?????
also ther gearbox is slipping pretty bad (getting rebuilt this week) could this be causing any of this
