Hi, everyone
I have a 19' Tayor ss. Im using a Edlebrock 4BL. On a 454 BBC. When the secondaries open, on occasion I get a loud popping sound fron the carb or air cleaner area. Again this only happens at WOT.If anyone has any ideas let me know.
Thanks

Lean. Big time. Look for a fuel delivery issue. Clogged filter, torn diaphragm on a manual pump. Bad ground on an electric. Clogged carb inlet, rust in the pickup, you name it. Bet you $5 you find something.

Go one step richer on your secondary jets or metering rods, read plugs

Any chance of water in the gas ?

jaquuuzz,water contamination causing pop,pop too.Check the fuel filter canister in the bottom of the fuelpump,when it gets 1/2 full of water you'll get popping in the carb.I would recommend a full size water separator at the fuel shut off valve that has a large capacity to contain water.As froggy said ,a lean condition maybe the culprit too.Check your fuel level in the bowls while running the engine at idle.Mr Gasket has the clear plugs for the replacement of the brass ones.

Corporate,
I had the same problem when I put the Edelbrock on my BBC. This past weekend I did some testing and found that the 6547 metering rods with the OE primary jets with the .110 secondary jets work rather well on my boat. It might be a good place for you to start.

this happened to me on a different engine. it was a bent exhaust push rod. slightly bent but bent.remove valve covers and roll them in place thats how I found my problem.
