Wilks, did you ever replace your glow plugs and, if so, did it resolve some of your hard starting? As mentioned, I replaced my glow plugs last season and the hard starting improved significantly. But the hard starting -- albeit not as bad as before -- is starting to reemerge. I pulled one of the glow plugs over the weekend to inspect and it looked good. However, the glow plug hole was filled with carbon deposits. Did you clean your holes out? If so, did you buy a reamer? Any advice would be appreciated.
