DOES A TWO-STROKE HAVE ANYTHING THAT RESEMBLES AN ACCELERATOR PUMP?
Yes. Some two-strokes use a power jet carburetor to provide an extra squirt of fuel. A power jet is an electronically controlled jet circuit that flows additional premix when engine rpm tells the black box to send more. A signal from the black box opens a complementary circuit, via a solenoid, so that more fuel can be injected into the combustion chamber. But, and this is the big difference, power jets do not work at low rpm. Instead, they feed in more gas when the engine is under its greatest load (typically from 8000 to 10,000 rpm).
