[Healeys] HS4 carb jet head and spitting - UPDATE

[john spaur]

All the presets; static timing, rocker clearance, points and plugs 
were spot on.

My HS4 tricarbs have plastic floats which are non-adjustable. 
However, there was a very thin fiber washer (stock) under the float 
needle seat. The washer changed the float level so it was out of 
spec. Removing the washer put the float level back to normal. 
Incidentally, the SU tuning manual states that float level is not critical.

Bottom line is I was able to setup the carbs and a little more micro 
advance (the knob on the distributor) resolved the spitting through 
the carbs. All is good.
