Am I asking the wrong question or does....

Hello All,

I have been trying to get some information on Weber IDA 48 and Ford 427 FE configuration. Is it that nobody knows the answer or and I asking the question wrong.

Please Help!

Hello all,

I am in the process of tuning my webers. I would like to get everything tuned and ready so I could just send out the body to get painted. Here is my situation.

The engine is a 427 side oiler and weber carbs. When the engine is idling I am getting a rich smell. When I rev the engine every so often I get a sneeze from the pass side front carb and driver rear carb. Also, I have noticed a flame from the carb would shoot up. Here is my specs on the carb.

Emulsion tube - F7
main jet - 160
air corrector jet 210
idle jet holder 120
idle jet 55- F10
choke 37
exhaust (bottom of bowel) 55

And need Needle valve specs?

Also I am hoping that somebody can include the measurements for the float with the 10 degree manifold. Also, I have purchase an inovantive LM1 wide band analyzer to help with the tuning.

Please help.

Thanks

I think the first thing you need to do is forget about using the LM1 and consider a simple Unisyn carb synchronizing tool like this.

or this

As the LM1 can only ready off the O2 sensor you installed, which may or may not have the capability to distinguish each bank, or each carb and it's particular tune. Keep the tune simple and use one of the two tools above and I think you'll find that your engine will be running much smoother in no time flat.

Thanks for the response.
I do have a Unisync and used it for the initial setup. I will give it a try again and see.
Would you know which Needle valve (value) is recommended for a 427 FE motor.

I believe ENZO at cobra accessories has a weber set-up on his cobra you can give him a call ,maybe he can help it's worth a try

Thanks for the info Cobra36. I will give him a call.
