It runs quite well pulling well from low down although could be a bit crisper and the plug is not black and fouling, a recent GPS run saw a genuine 70 and that was in the heat. It starts first or second kick and idles reasonably smoothly.
Having read a large number of other setups I've noticed my main jet is relatively small but I'm running a rich slide, it does spit a fair bit of fuel.
I've got it on a solid manifold and I assume as a consequence they are light shiny patches on the slide and the inside of the carb body although I don't think is significant wear.
The engine is in good order, the SIL crank failed recently so I treated it to a new MEC one and bearings, the bore and piston are fine and it has loads of compression.
The local gurus seem to think the issue is solely down to thrashing everywhere but I think there must be room for improvement without investing in pipe and slippers
