Hey, I have a Yanmar 155D which is not a great starter in cold weather (pretty much anything below freezing). The thing runs fine once going and warmed up a bit (smooth running with no smoke or blowby). I have checked the Thermostart device and valve timing - all OK.
One thing I'm wondering about is winter vs summer diesel. The diesel I have was bought some time last year so I am not sure whether it is summer or winter blend. Is there any simple way of telling which (I will replace the diesel in tank with winter blend if it is summer in there now)? Would it make a great deal of difference in cold weather starting?
TIA for any comments...
