Trying to figure my farm hoe out .. 2005 320 cat with a 3066. It sat for the summer. New batteries , new fuel filters, i added some 2 cycle senthetic oil to lube up system and howes conditioner and it still has a fuel or air problem . I can start and leave at high idle but when I go high idle and start to work she sputters like lack of fuel and pushes white smoke and eventually dies . Haven’t checked pressures yet , hope it’s not cracked head .
Did you check for water in the diesel/tank?
