rough running / non starting Options

[JFG]

The other day i drove my car for the first time, properly, and did a six or so mile loop just about.

The car started popping and losing power momentarily and i just made it back onto the driveway.

It was fine when cold but when it got hot the above started.

This morning i turned the key and it fired up straight away so i pulled it out of the garage for a check over.

I took the plugs out, they were slightly sooty and gaps are at 0.60mm on ngk bp6es iirc.

When it was back together the bloody thing would not start at all.

Lost my cool, nearly, and pushed it back in the garage.

Tonight i tested the coil and there is a good blue spark on the test plug. so i'm thinking the coil and electric ignition module in the distributor are fine.

My fuel pump is up under the tank and that is running no problems.


My next check is to see if fuel is getting to the carbs, i find it odd that despite the pump running and plenty of fuel the plugs were not flooded or even wet in any cylinder.

My first thought when it limped home was fuel evaporation but i'm not so sure now.

More checks to follow

i fitted the new inline filter and flushed old petrol from the lines past it

i did get a couple of times where it tried to fire up but nothing more. so i'm now stumped. i have spark, compression & fuel & 12v at the coil

however when i take the middle ht / cap lead out of the dizzy (from the coil) i get no spark at any distance, when i put a spark plug in i get one spark then nothing. i do get spark at the plugs though!!!

could this be ignition switch?

The center post or coil lead connection at the distributor cap may have a problem letting the spark get to the rotor, and then all the way to the plugs. Rotors with an internal resistor are known to go bad. If you don't have a good spark indicated at each and every plug consistently, then check each ignition component from the coil to the plugs, i.e. full tune up, points, wires, rotor, cap condenser, etc.
