Have just developed a weird sort of misfire on my Veccy.
Only happens at low revs under load , normally in 2nd and 3rd gear, betewen 1500 and 2000 rpm.
Its just like it misses a heartbeat and then recovers ok.
If driven hard up through the gears it is fine.
Have checked vacuum hoses and connectors and all are fine.
Have added some injector cleaner to fuel and given it a good blast out but the problem still exists.

Anyone any ideas where to look next?
