Esso petrol contaminated with water or stale petrol

Dependant on which carbs are fitted, the remote float bowl type you can just take the top off the chamber to have a look in there and see what's really in there regarding bits of anything or water etc.

Yes it’s a Rover P6 2200 TC 1976 it has a   AccuSpark Electronic Ignition Performance  kit fitted so no points checked carbs took tops off and sprayed carb cleaner in them to clear any blockages and put some three in one oil in the tops checked spark plugs yesterday they were all sooted up one of the plugs the electrode had broken away so will have to replace it as I,ve started to drain all the petrol from the tank as I still think it’s down to the petrol I bought from esso as the car was driving lovely before I filled up with there petrol as I think it’s contaminated with kerosene as someone said on here about another petrol retailer as when I set a light to a little drop of it a lot of black smoke came off it and a very bad smell came off it and yes the Rover is well designed you can unbolt ever panel off it and it’s been well looked after no rot in the usual places only a couple of rust spots one in the boot and two on the rear panel under the rear windscreen what the rear scuttle panel bolts to all the running gear is in good condition thanks

Am I right in thinking your Rover has twin Stomberg Type Carbs - does E5 & E10 attack the rubber type carb diaphragms or have you changed them to Vitron to resist the Ethanol?

K2-K6:
Oooh no Ted, that was the Triumph motorcar that used those  ;D ;D

Said in jest, because the first Range Rover V8 was on Stromberg, apparently for better tolerance of angle, off angle, when typically used on that vehicle.

There was apparently some sensitivity to slide damping on these 4 cylinder Rover engines during development of twin carb setup (hence my question about oil in the dashpot) that caused "flutter" or odd closing of the slide when it should be open.

McCabe-Thiele (Ted):
Sounds unusual but our old 1275 S had inch and a half SU's that I changed to inch and a half Stromberg's as they were more responsive and easier to get the mixture right iirc it was an Alexander conversion.
