I'll start with a little history. I generally start the motor per the manuel with one pump of the throttle to prime the engine and then crank with a quarter throttle. It generally fires right away. Once it does I slow the motor down to a 1000 rpms. Once the operating temp. starts to rise and the rpms start to climb I can idle it all the way down and depart. This has been standard operating procedure since I bought the boat several weeks ago. I've been using the boat once a week since purchase so it wasn't through inactivity that I had a problem this past weekend. After starting the motor and letting it warm up at a high idle, the rpms never increased as they usually would have. It didn't pay much attention to that but when I tryed to idle the boat all the way down it stalled. I was able to start it a couple more times using the same procedure but was unable to get the boat to idle without stalling. A couple attemps later I could not get boat to fire at all. At this point I went through the normal checks. Plently of fuel pressure. Plenty of spark. Consequently the plugs were not wet with fuel when I checked. I finally got the engine to run by having someone manually hold the choke plate open on the carb. long enough for the motor to fire and clean itself out. It then took about 15minutes of operation to clear the excess fuel and fouling out of the carb and engine. It ran and started fine for the rest of the day. Could I have simply flooded the engine? If so why weren't the plugs wet with fuel? I used the same starting procedure as always. I'm new to carburation. Is there some kind of float mechanism that would allow fuel to pool up in the carb and not flow into the cylinder heads? Could the choke be faulty? Any suggestions would be greatly appreciated.
