Hi Guys,
I would really appreciate some experienced help in getting my CAV GT40 running well. It is fitted with a 347 Boss Ford Crate engine running with 48 IDA Webers and MSD ignition and on NGK BCR8ES plugs. The symptoms that I have are that the engine runs smoothly on idle but on (very) small throttle openings the engine backfires through the exhausts - suggesting that it is starting to run lean? The top end performance seems fine.
The carbs are set with the following jets:
Idle 70F10
Main 135
Emulsion Tube F7
Air Correction 120
Choke Size 37
Can anybody tell me if these settings seem about right? Thank you!
