Have set electrode gap (& cleaned) whenever I stand in front of it .. it fires up on first spark ... I know it can have multiple attempts.
I'll disconnect the water trap connection for a while and see if that makes a difference.
I noticed that it is about 3/4 full. ... both sides
Since I removed and cleaned it fully ... left hand side wasd empty and right hand side 3/4 full.
I assume that is what it should look like in service?
My mate has the exact same problem , if it anit the above what else could it be ?
