Gas poured into the engine from stuck floats

[patssle]

One of the floats on my Webers got stuck and some gas poured out into the intakes and down into cylinders 5 and 6. Luckily I limited it as I was behind the car manually connecting an external fuel pump for testing purposes.

Not sure exactly how much, but it was at least a 2-hands-cupped handful. Any thoughts to this situation? Somebody recommended I pull the spark plugs and turn the engine over so it pushes the gas out of the cylinder heads?

Thanks.

I wouldn't sweat it too much. You can pull the plugs and turn it over using the starter with the coil wire off so the engine won't fire, then just let it sit and it will disapate. Take a look and smell the oil on the dipstick too. If it seems thin and runny and smells like fuel, then change out the oil and filter. Since it was not a long term issue I doubt any damage occurred. Good Luck.

I would be pulling the plugs on whichever cylinders were flooded, disconnect the coil wire and ground it, then crank the engine for 10-20 seconds until its cleared out.

I had a problem with my injectors staying energized after I turned it off. The engine totally filled with fuel overnight to the point that fuel ran down the driveway. Because there was so much fuel I ended up pulling the plugs and cranking it to clear the fuel. I also changed the oil because it was obvious fuel made it past the rings into the oil. Don't try to crank it with the fuel in there. If one cylinder is able to fire the cylinder with the fuel will bend your rod during the compression stroke. It happened to me once before and I ended up bending a rod the 1st time. If you have any concern over having fuel mixed with the oil, change it. Cheap insurance in my opinion.

Just went through this last week with my T4 motor in the 912. I have 45mm dellortos on my 2.2L motor, and, and I had a scare when I went to start the engine from cold and had what I though was an engine seizure.

Turning it over by hand, I found a spot where I could not turn the crank further, but it did not feel like a hard seize, rather more like something soft was jammed in a cylinder. Then I noticed the gas running out of the base of the carb. Talk about getting a clue!

The plugs were soaking wet, of course. I cleaned and dried them, then let the motor dry out as others have described.

I discovered when I pulled the top off the carb that the float jet needle had a pretty severe groove worn around it. I replaced seat and needle and all is well again.

Appreciate it guys. Took out the plugs and turned the engine over - gas came spitting out. Going to let it dry out the rest of the afternoon. Then while I'm at it, put some hotter plugs in to figure out my Weber issues (exhaust popping).
