I am not implying that the oil I used is responsible for the blockage.
I believe the jet was blocked before I started messing with the engine, the crud in the crankcase sitting on top of the lip the gauze sits on was something I have not seen in an Austin 7 engine before, it was the same consistency as the crud that was on the allen key when it came out. The oil pressure was high from the first start and run, it was never ok.
In hindsight I should have rodded the jets out before I boxed the sump up, but I didn't. I should have done all sorts to it, but the idea was to drop this engine in as a temporary measure to take the pressure off sorting out the problems with the 'good' engine - or rather the one with fairly fresh pheonix crank in it. Hopefully I've got to that point now!. In anycase at least when this engine is removed from the car, I've got a running engine ready to drop in my tractor project.
At present I'm using Carlube 20/50 in this engine, and I note from the tin that it is a non detergent oil, which I hadn't realised when I bought it and was not my intention. I usually use Halfrauds or Wlikos Classic 20/50, sometimes the Comma branded product (all the same oil). Sometimes Morris also. I shall top this up with some modern oil to add some detergent. Its just had an oil change so I'm not doing another one yet!.
The 20-30 mile oil that came out (I always change the oil very soon after being in a crankcase) came out pretty clean. It didn't make the shed very black when I painted it with it.
