I have a 1966 +4 with a TR4A engine rebuilt circa 5 years ago. Two issues have become apparent in the last 3 weeks :-
- took it on the road 3 weeks ago, started fine but under drive was periodically misfiring....seemed to cut out then go again.
- started it today ok, then suddenly misfiring and back firing before cutting out.
Have done plugs, plug leads, distributor with new points and condenser and fuel is fine.
Could this be a faulty coil ?
Many thanks,
Dwin
