I know about the 603, so please don't start a debate on 617vs.603. Also, if it was hard to start at 8 degrees and needed a jump then ran rough afterwards, would the hard starting be the battery? Or, would it be more of a loss of compression? I didn't think that the mileage was the high considering the rest of the SDL's around.
Thanks again
David
