I just tried starting my stock '55 292 with ECJ 9510G Holley "teapot." It had been running perfectly when i shut it down a year ago. It started immediately and ran perfectly for a few seconds on the gas prime i put into the carb. However, when the fuel pump kicked in i could see spurts of gas coming out the top if the carb, just under the air-cleaner bolt. It ran very rough for a minute or so and then died. Tried it again with the same results.

I'm hoping there is a simple fix for this.  Any suggestions?

Id guess either stuck or sunk float. I think that would hold open the needle and cause your problem. Others may confirm

Hopefully not too serious!

Depending on what type of needle is in the carb it could be sticking.Most of the newer carb kits use a needle with a "soft" tip.They deteriorate because of all the additives in todays gas.The originals were all steel and used a clip to attach to float so the needle moved in sync with the float.The new carb kits do away with that clip which also leads to problems.If the needle is the problem the original all steel ones can be bought through the obsolete parts dealers.You might also check the presure output of the electric fuel pump..Too much pressure can force the needle open leading to flooding.If you have had no trouble previously I think I would be looking at the needle and seat in the carb.

Just reread your post.Are you using an electric pump or just the original mechanical one?

  

Ron and Mark, thank you for your replies. Based on the car sitting for a year, I'm pretty sure either the float or needle valve is stuck.

Mark, it's a mechanical fuel pump, all stock.

I was just checking my parts book.I dont see an ECJ-9510-G carb.Could it be ECZ-G which is the same type carb.If  you look at Ebay # 140548764255 that is the original replacement needle and seat.Steel with the clip.If you take the round cover off yours to check the inlet needle be careful with the gasket.Can be pretty fragile.Part# on it is 8CM 9945.

  

It is interesting to read this account of a flooding teapot carb. Some people dispute the reputation that these carbs have, the 'towering inferno' reputation.



You might consider looking for a WCFB Carter 4bbl to replace that Holley.

The Teapot is about 400CFM as I recall.I replaced mine with a 390 cfm Holley.

  

Something to also look for/at. With the air cleaner removed, there is a brass screw about 3/4" in diameter that is angled and located on the fuel inlet side of the carb at the top. If this screw comes loose, or if the gasket fails, the carb will send fuel out. This screw is the item that gave the carb the "Inferno" name.
