Hi

I have a rv8 4.6 with webber 500, all is new and has been working fine.
Started her up to day to warm her up and she was running terrible.
Took off the air filter and all four barrels of the carc are full of fuel.
With ignition on the fuel pours into the carb like crazy.
Could this be a float problem? Its strange as the car was running perfectly the other day.
Could i have damaged the engine trying to start it with all the fuel in the carbs, it was running but was running real bad.
Any advise would be great.

Cheers
Chris

Possibly the carb froze when you started it up - damned cold outside today - I just took down some Xmas decorations and damn near frozr in 10 mins!

Damp atmosphere, cold weather and evaorating fuel causes icing in a big way

Found the problem!
The driverside metering rod was bent! and therefore not returning to the jet.
Has anybody ever had this before?
If i replace it will i have to adjust the spring to stop this happening again?
Your thoughts are appreciated.

If you do get it fully straight the existing spring should be ok. My concern would be why it got bent after so much good running?
There is nothing that could put so much pressure on it to bend the rod??

Did the fuel pour out with the ign on from all 4 boosters??

Flooding like this could be excess fuel pressure - punctured float - crap in the needle jet (s) - float level too high or air horn booster gasket leaking.

Depends on where you actually saw the petrol coming from?
