I have a rochester quadrajet carb for my SBC that I just had it rebuilt and it is worst than before. My carb started leaking from the gaskets. The float was getting stuck Gas was getting stuck in the carb and not going down into the intake, My truck would start and shut off after a mile at normal temp. I decided to get it replaced or rebuilt. I found a place in Las Vegas with really good reviews. I called them and they said they would give me a Reconditioned carb for 245.00 if I left them mine as a core. I agreed and they told me it would be 2 hours for them to get the replacement from their warehouse. I come back later,they tell me they are testing the carb. They were so nice I decide to pay before i saw the "new reconditioned". He brings it and it looks like they cleaned my old one and put new gaskets in it. I ask if that was my old one and they say that yes it was.it was rebuilt and show me the receipt and indeed it said rebuilt.(my fault for no reading the receipt) I have a 90 day guarantee if I install it my self. Forward to earlier today, I install the carb and crank it. The carb starts leaking like crazy from the spacer/gasket. I take the carb off to see if I left anything inside.--nothing was blocking it I blow where the fuel line goes and its clogged I turn the carb upside down and a bunch of gas falls off i check the carbs fuel filter-its new I blow where the fuel line goes and its clear now that there is no gas in it. I install it and i crank it and this time it leaks from all the gaskets. I remove carb and flip it- There is more fuel inside the carb than before. I shouldve bought a new one for 400 but now I get to call them and tell them that is not fixed,drive 100 miles to take it in and hope that it is fixed for good. THe QUESTION IS: Should i spend all that time and gas money to take it back to them and have it fixed or could I fix it my self with your help and save me all the grief going back and forth dealing with one more pos mechanic???
