Just replaced the glow plugs in my Branson 4720 tractor. That cured the hard starting problem I was having. Started right up strong at 12 degrees with a dead cold engine. Thanks again Ken of Valenti's Tractor Valenti's Vintage Vehicles L.L.C dba Valenti's Tractor
Now for the worry. Two of the plugs had slight black smudge deposits, but the number 1 and 2 cylinder plugs had white rings around them where they were inside the head. If all the plugs were the same I wouldn't be as concerned, but 2 plugs with black deposits versus 2 plugs with white deposits have me worried. I attached a picture of 1 of each of the old glow plugs I replaced to show the difference.
Do any of my fellow TBNers have an opinion what caused this, and if so, is there anything I can do to fix it before it becomes a larger problem?
