I finally got my new starter for my new to me l245dt. I bought it not running a couple weeks ago and hadn't been started for almost 3 years. It started up without too much trouble using the glow plugs it would start and stall after a few seconds and eventually got it to stay running. However it will rev up and down on it's own. The linkage to the throttle lever on the injection pump moves freely. With the hood up I can watch the arm move and there seems to be a large dead spot from idle to about 3/4 throttle. Once it gets to that point it will rev quite high and stay there without holding the foot throttle down. I have to pull on the hand/shut off throttle to bring it back down to the point it shuts the fuel off before it will calm down. I sprayed some fluid film on the arm on the pump but it seems like whatever that arm on the pump controls inside is sticking possibly. If I quickly run the throttle arm wide open to idle with my hand it seems to rev up and down fine right back down to idle. And stay there. But if you do it slowly as you normally would there is that large dead spot where it won't do anything untill it revs way up then won't stop till you cut the fuel off
