carb flooding

I recently purchased a rebuilt holly carb for my 3 cylinder gas tractor backhoe from yesterdays tractor.When it arrived, I put it on and the first time I cranked it gas poured out of the carb.I thought the float was stuck,took it apart and it was free,and closing the needle.I noticed that the small spring on the float shaft was missing.I put it back on as the float was not stuck and moved up freely.Gas poured out again.I contacted yesterdays and sent it back.It was taken all apart,a new spring put on,checked out,and sent back.I put it on again and it flooded but not as bad as before.I don't see any reason for this happening.I even changed the fuel filter before the gas enters the carb.The problem appears to be the carb.If the needle and float are free and working,how can it still be flooding? Any help will be greatly appreciated.Thanks,Marc
 
The float may be set too high... You would need the spec for that carb to reset the float to the correct height. I would think they'd have checked that when you returned it... Also... the fuel pressure could be too high if you were using a high pressure aftermarket electric pump or something...

The spring is there to pull the needle open,not to close it.Float level is not critical.Float rubbing on the bowl will give trouble.No gasket on the seat will cause flooding.
 
ditto what rod said.. what fuel pump you got?

have you checked the seat for a gasket.. anv you adjusted the float a lil lower as a test?
