Thomas,

The groups responses are all correct but do not address what is probably

the root of the problem. My 1988 RX7 began flooding at about 90,000 miles

(a common problem of high mileage Rotarys). The reason is leak down of fuel

from worn injectors (they remain under high pressure on shutdown of engine).

The solution is to fabricate a bypass to bleed off fuel pressure to the fuel

return line to the fuel tank. This can be done with a few brass fittings in an

"H" shape. One side of the "H" is fuel from tank under preassure. The opposite

side of the "H" is fuel returned to tank. The cross link of the "H"contains a

plug with a .020 to .030 opening to bleed off fuel pressure after shutdown.

The fuel pump has plenty of excess capacity for all normal automobile

operation and the fuel pressure regulator will compesate for slight loss of fuel

pressure. Cured my flooding problem. FWIW
