If I understand what you mean by flutter then yes they do. We had a L combine that had a 426 that did that when the temp was much under 70 degrees F outside.

Both the 7000 and 7040 I've had did the same thing when cold, especially under 70 degrees. Run fine warmed up, just don't start well cold compared to other engines.

by flutter. I guess it sounds almost like a miss. but not quite. hard to explain. thanks for reply

I had a 7040 that I would say ran choppy at first ten smooth out. my 7060 and 8070 don't.
