The fuel injector circuit is now working. I connected the circuit to the 12 volt battery and put the fuel injector in the circuit (across the back emf diode).
The simple fuel controller LEDs are flashing and the carburetor cleaner is coming out of the fuel injector nozzle in squirts.
I also have the 555 timer and the MOSFET connected to the 12 volt battery.
The carburetor cleaner is simulating pressurized gas to the fuel injector. The fuel injector control circuit is on top of the cardboard box while the lawnmower battery is to the right.
I will solder the circuit on a board then try it by squirting liquid propane (LP) into the carburetor of a small gas riding mower.
After that I will build a pressurized gas system and try to burn gas in the riding lawn mower using this injector and circuit.
