Tune Up advice 8:71 Birdcatcher & Mech Alk Inj, 110 PU
This is my first experience with a blown alky engine. I have a 540 ci BBC Merlin three block with Big B. 3 Heads, 8:71 Hampton supercharger, Enderlie 110 Mechanical pump, Bird catcher, with only hat nozzles, Debating on the port. It's at 50 % overdriven and I don;t know much about the rest of the engine. It was an engine I purchased from Bowers in Co. It didn't have the rods, crank, or pistons I paid for, as well a host of other things. I saw that when I pulled the pan. The theif sent me Scat rods & Crank and pistons. instead of the Callies Crank, Manley Rods and Airies pistons he was paid for. BACK TO TUNE UP Compression ratio, Cam and Head details ?????Yhr engine required that I swap 4 and 7 plug wires to run. It sounds crisp, and strong but It is so rich. Where do I start?

What size are your jets? Are you running alcohol or fuel? I run a similar application and the jet in the barrell valve is 110 on alcohol.
Bird or buzzard catcher?
Do you feed fuel at the catcher and in the intake or just at the catcher?
