I just bought new glow plugs and fuel from my lhs about 1-2 weeks ago. I took the air filter off my engine and my carb looks clean, I also have a Dubro in-line fuel filter. By the way, my fuel tank has a primer built in, so I sure it's getting fuel. And I've only been trying to start it when it's about 90-100 F because it'd be easier. Just so you know, it's 10:15 A.M. here and it's 71 F, but it'll get up above 90 by noon and won't go below 90 until about 7 or 8 o'clock. It does start every once in a while, but it dies quickly, especially if i touch the gas at all. It's been easier to start if I warm it up with my sister's hair dryer.
