So I did the leak down test 6psi for 6 minutes. Had a leak around the boost bottle the metal clamp is stretched so I bent it to make it tighter. It passed the leak down figured it would be all good and nothing. Still has that bog when you lug it and it start to pull in its powerband its like a small hick up. I have 290 mains and stock pilots and the needle is on the second one up from bottom I had it in the middle but still the same any ideas? Btw idles great now that the carbs where synced. Thinking abt getting new clamps and just a cross over tube and then see what happens.
