What have you done today with your Austin Seven

[Terrytuned]

Carb checks- too thick an oil in the in damper will cause poor acceleration use 3in1 oil or similar. check piston lifts and falls freely if not centralize jet or clean dashpot, to centralize jet screw jet nut up until jet is level with bridge piston without damper should drop with a slight clunk on to bridge if not release nut above jet spring and tap lightly to centralize check after retightening you may to do this several times. To check float level remove dashpot and piston with jetnut screwed down 8 flats turn on fuel or pump, fuel should not flow over the jet operate choke to lower jet fuel should flow over jet. A blue spring is correct the needle could be AN,4,5,or 6 depends on any engine tuning. Basic setting is usually
8 to 10 flats on jet nut when engine is at running temperature lift piston slightly if dies too weak if speeds up too rich adjust one flat rev engine
 then check again, for overall setting you need to check on road.
