Scott I will check them, I have an on head checker. But the weird deal I definitely buzzed it 7000 in first and there was no issue on the run it was the worse. So I would expect soft springs to do it consistently at the same rpm , but I could be wrong. And when it did the weird eal it buzzed to 7K real fast and no "shooting ducks".
