Has anyone noticed a shutter on acceleration at approx 2800RPM in all gears.
I assume this is the start of ignition timing advance and their is a time delay in this. Planting the accelerator when it does this gets rid of it, but if cruising it can continue for a few seconds...

Either that or a critical frequency in the Clutch/Flywheel set up.

Might be totally wrong on this, but am Interested to hear from forum members on whether they experienced anything similar and how they rectified it
