RE: [Chrysler300] Carb flooding

Also, Make sure the seats for the needles are tight in the carb top. I had this happen on my wife Deb's AVS. after having rebuilt it myself. and on a friends AFB that had been sitting for some months. Rick

I have read that the viton tips can be problematic when used with Ethanol gas, they start leaking for whatever reason. Some performance gurus recommend metal needles. Also might make sure that one of the floats hasn't opened up and started to sink, although I wouldn't think that would happen on both carbs at the same time.

Image removed by sender.It must be because they started to tear down the Carter plant yesterday (see Hemming daily news yesterday)… Anyway I reinstalled the induction system on a G and had flooding at both carbs. I mean the fiber mounting gasket became soaked and bled through to the periphery. On removal of the carbs there was liquid gasoline on the bottom of the intake manifolds.

The previous work included removing the intakes and reinstalling them with new gaskets and new carb mounting gaskets. The mounting gaskets were Felpro .125 thickness fiber with separate holes for each bore (no cutout of the gaskets between primary bores or between secondary bores. The carbs worked well before removal and were not opened as part of the work.

Since the fuel lines were worked on I thought maybe some dirt was preventing the needle valves from seating (though I flushed the lines before installing). I checked fuel pressure at the carb inlet from the electric pump and it was 4 psi so it wasnâ€™t overpowering the valve. Upon taking the cover of the AFB off, the bowl gasket had been sealing well with no leaks. The needle valve and seat had no apparent dirt and the Viton tip was flexible. The floats were intact and swiveled freely.

Anyone know of some other issue(s)/system(s) (in the carb or not) I should check that may cause this type of flooding? Thanks.
