ok lots of things to look at here. Replaced coil. No difference. Had it running last night with a small miss that goes out when raising the revs. I have NGK plugs which many people do not like. I cleaned them and reset to .035" as they were smaller than this, ran even rougher. I have ordered some autolite 303 plugs but not confident that will make the diff. I rechecked that rotor is pointing to number one lead on cap at TDC. Now here is the funny thing, at rough idle I removed each lead to see if it was a single plug missing. I went through all leads and it made no difference at all. I even removed 2 leads (5 and 6) the same time and there was no noticeable change at idle of the misfire. Was going to put a new carby kit in it but the condensor will be my next effort I think? I will loosen fuel cap but I had the tank out recently and all lines are clean and clear with no rust. She really does not like be set at TDC likes 5 to 10 before but still misses. When the revs are up it runs ok. Plugs were very sooty but not oiled or burnt or wet. It is running rich as it is fumey when idling.

Hi all, First time poster long time reader. OK car now starts and idles well cold. Has new points, plugs, vacuum control, new leads. Leads are in correct order. After reaching a operating temp (5 mins running) it starts to miss and then lacks power and then dies. Random small backfire. I have checked timing currently 7 degrees approx BTDC. Will not start again after heat cycle but will when cold. The best it would do is start and run like it had racing lump cam in it, fire almost die and fire etc etc then will die. I have played with air intake screw and that seem to be OK at about 1.5 turn off fully in. Choke is not stuck. Fuel is clean and supplied via a new electric pump out of a recently de-rusted and treat tank, also new fuel lines. Motor is old but has no head gasket issues (good radiator and new water pump) with consistent compression across all cylinders. I am replacing the coil in the next days or so. Suggestions as I am running out of ideas? Perhaps running 91 with lead additive my plug gaps might need to be different to book? Points are set to .20 thou. There is a little play in distributor shaft, would this cause this?,,,, but cannot see why as this was the distributor that was in it when it was running sweet. The car has not done a lot of work in recent years and was running fine out of storage. Did a refresh and now this happens. (note to self : don't fix unless broken.lol). Cheers Spiny.
