I completely agree that it is a matter of opinion and my opinion was stated in jest. I am also aware that they are not the greatest of engines with better diesels available, and in like for like with a good condition petrol are not as refinined or powerful. However, you will not change my mind and all of the threads about missfires/carb problems only go to strengthening my opinion that I would rather have an oil burner than something which, for no other reason then it feels like it, decides it is not going to run properly today and doesn't like getting wet
