Oil fired furnace help

[OILFURNACEPRO]

I have seen a lot of questions about oil furnaces, such as what is wrong, the age of it, parts, etc.  Born in the mid 1950's, I have worked on oil furneces for three decades and I am a mechanical engineer.  I am offering free common sense advice for those who have questions about the above items.  There aren't many HVAC companies that will even look at waste oil burning furnaces and just want to sell you a whole new set-up.  I am offering unbiased information, especially for those who have older oil furnaces, to help with options regarding this expensive decision, looking at home value, practicality, efficiency, financial and environmental impact.  Questions on all other types of furnaces welcome.  I hope I am not violating any rules, here.  Thanks and just saying...

Hi

I’ve noticed my oil furnace's flame flickers sometimes , could this be a burner issue, or should I check the oil line or filter? Any tips would be appreciated.

Oil furnace flames always flicker, don't they? 

Or is this flickering somehow unusual? 

When was the last time it was serviced. With oil furnace's you really have to service them every year. Get a new filter and nozzle in there.
