It has never flamed once, but another racer has the same motor (not moded) and his was flaming. I never had a chance to talk to him about his motor. I ran mine rich some and ran it not soo rich and it still ran fine. After every heat I was constantly leaning it. Temp never above 180 so it was not even close to race tune after a 20 min main. I could still lean some more. It ran not matter where it was tuned is why I am asking about tuning and flaming out. There must be an envelope that too rich or to lean but, in between those points it will stay running. I have tuned alot of airplane motors but, the race tune on these car motors is what I have to learn more about. The 2058 pipe is the the perfect pipe for the B-6 and the best part is the sound the 2058 makes.
