Well, lots of people are laughing by now see the title of this post... but after all the usual things are checked and ' set' ... and you still have a 'efficient burning of diesel fuel ' problem... it is time to pull the precombustion chambers and see if the tiny holes in them are plugged up... or if the Pintle is fried and laying in the bottom..... and it is not very hard to do... fortunately.. but many avoid it for some reason.... when you have them out you may can borrow a bore scope and look at your valves and cylinder condition also....
Ok,,, yall can stop laughing now....
