no ignition

I have a WH Olson Manufacturing oil furnace Mod# WTL100
Ran great for years changed nozzle every couple of years. couple days ago wouldn't fire have fuel to nozzle tube, burner motor runs but no ignition.is there a way to check ignition coil or electrodes.do the electrodes have to be adjusted every so often or do they go bad. pulled everything inside the tube where the nozzle tube and electrodes run cleaned and reassembled putting electrode tightener screw in same mark as previous on the nozzle tube, no go.

Welcome to the forums.

The HV transformer should be on a hinged plate and should be checked for spark.
Be careful.... there can be lethal high voltage on those spring contacts.

Do not use a meter to check the secondary voltage. You can use a tool with an insulated handle to check for voltage at the springs. See if the spark will jump a gap.
