Carb flow sensor & speed sensor

the flowsensor has a 1.3mm orifice at the inlet to the paddle wheel ,even though it has a 5/16" hose fitting ,I am hoping adding more sensors will allow it to work with lower flow rates.

As for the speed sensor ,see attatched picture ,it uses the same hall effect sensor I have used to mod the flow sensor .
I have left it unpotted & exposed until I have tested it further.
So far the speed sensor works ok & it's simple (three electronic components & two magnets).
