Timing is ok i think, i havent changed anything since it came back from the garage and it was fine when running and starting from hot, just when it gets cold. used to be able to depress the plate under the airfilter on the metering unit a little and it would start but not now with this new metering head ( the main reason i changed it was because after i took the co2 adjuster off and put it back on again and also depressend the paddle right down it was starting but only running on 3 cylinders so i figured i had knackered the metering unit or somthing?

it was always slow to start on my old engine and i had to play with the throttle but it wasnt that bad. the only things i havent changed now is the metering unit, fuel ecu, wiring loom and gearbox everything else got changed when i did the engine. I got a superchipped ecu and put it mad sure it was the same year as before ie hearts and diamonds. So im thinking somthing to do with the plugs at back of inlet? metering unit or fuel ecu? what do people recon?

Also the two plugs at the back of the inlet manifold one is definately light brown i've tried cleaning it and it is 100% light brown. i had the cols start valve off and tried switching plugs around and it squirts out with the light brown one on but not with the dark brown one?????? Im baffled???
