Furnace has strong, sub woofer like rumble, and electrode constantly sooted

Hello, I've gotten my furnace running and not leaking a huge amount of oil underneath anymore.


I'm now trying to solve two issues with it.

The first one is that it quite often rumbles somewhat like a sub woofer when running and can be felt throughout the entire house while it runs (first 5 mins or so are strongest and rattles the heat ex changer).

the next issue is that the electrodes are constantly getting soot between them and causing a short preventing them from starting about once every 4-5 cycles.

The issues may be directly related, could it be perhaps running too air rich or lean? or have some other airflow restriction issue?

Sounds like you may have an Air/fuel ratio issue.
Not knowing the history of your unit, when was the last time it was cleaned, filters and other consumables replaced?

I ramped up the airflow and Its far less intense, I also vacuumed a huge amount of debris out of the duct going to the chimney, what is the likelihood of a restriction in the heat ex changer?

Is there any reason you are running such an old system?
I'm assuming it's not a nice looking show piece (like my 1930's piston pump I still use).
It sounds like you are having issues with it. Might be time to concider replacing it and saving the trouble and fuel costs.
