Hi any suggestions on my issue?
1293 twin Su's new 23D dizzi,new plugs/leads,new loom,orig alternator and coil. has run ok for about 500 miles.
Problem is running on 3 cyls most of the time but will occasionally run on 4 for 20/30 secs, av tried removing each plug lead
one at a time but makes no difference.plugs are gaps are ok, alternator is charging, dashpots are free to move.
