Hello. I have a 2004 diesel lazer z 72" mower. At the end of last year it started losing power at high idle. So...I bought a new fuel filter and it ran great for about an hour then stopped running all together like it was running out of fuel. So it sat through the winter and I'm just now getting the time to work on it.
I bought a new fuel selector and it idles again but as soon as I put a load on it the engine goes from running smooth to bogging down and spits out a white smoke out of the exhaust.
Any ideas?

Could also be the injector.
