Abstract An auxiliary fuel supply system is provided for a two cycle internal combustion engine (302). first fuel line (350) supplies fuel from the fuel pump (338) to a solenoid (352) which is continuously cyclable between ON and OFF states during running of the engine, including high speed operation where detonation may occur. Fuel then flows through a second fuel line (354) to a restriction orifice metering housing (356), and then to a plurality of third branch fuel lines (358, 384, 386, 388, 390 and 392) for delivery to respective cylinders. The restriction orifices provide a pressure drop from the second fuel line to the plurality of third fuel lines, to provide lower fuel pressure in the third fuel lines, to reduce the chance of leakage at the intake manifold (326), and also to reduce fuel pressure fluctuations in the third fuel lines otherwise due to cycling of the solenoid. Metering housing structure is disclosed. The solenoid is controlled by a variable duty cycle oscillator (408), which in turn is controlled by a fuel enrichment signal (84) output by an electronic control which is responsive to engine knock and/or temperature. Control circuitry is disclosed.
