We just ran in one Rossi Q40 engine the old skool way ... as usual use a prop of 1" smaller then we ran her about 2-3 tanks semi rich. After that it was running for about a whole gallon of 2-3 mins blubbering rich and peaking it for 30 secs. Pain in the butt but she was running so smooth after that. I ran in my Rossi 45 by running her rich for a few tanks then was off flying her.
This is good for an ABC/AAC engine????????
