Furnace will start, and run for a while, but at various intervals will shut down w/o reason?

Primary Control goes into a 'restricted/lock-out sttate, but seems I can always reset w/o issues. When I do reset and furnaces starts, I get a huge plume of black smoke, ejected out my power-venter. I suspect this as a result of built-up oil, inthe burner chamber which did not origianilly ignite?
Guessing?

Next step will be to call Weil McClain to get some input from them. Maybe mu issues, is something, common to this brand of furnace, that requires specific settings? Also have called another P & H contractor recommended by a Forum member, and will be coming to house to review the issue.

Thanks,

Hi Bigdog
Im a tech for a large oil company . from what you are discribing everything is working right up to the point of ingition ( I get a huge plume of black smoke, ejected out my power-venter.) you need 3 things to make combustion you also need them in the right amounts to much air will lean out the mixture to the point of not firing. to little spark will also not let it fire
