If you search the archives on "Lawnmower Syndrome" you will

also find similar problems. By any chance did you start it

for a few seconds (as though mvong the car to get the lawnmower

out) and then turn it off? That can lead to a similar problem.

Paul listed all the common things to do to help. I'd also

consider changing the oil since quite a bit of fuel may have

washed down the cylinder walls into the engine.

By the way once it floods it is very hard to start since the

extra fuel keeps the piston rings from sealing (so no

compression).

Our 95 has seen the problem twice. My S70, never (but it is

frequently run to high engine RPM which helps the valves to

rotate in their seats, reducing carbon build-up).
