G'day folks,

I'd recommend going for the NGK BM6A plug - from my time in the OPE game I don't think well of Champion plug quality, and they're no cheaper. Set the gap to 0.025" before you install it.

Any of the motor trade parts supply shops [Repco, Bursons etc] will have these on the shelf, at a better price than the like of Bunnings or mower shops.

Re the catcher crack, these catchers are made from Polythene, which isn't really glue-able. Plastic welding with a polythene filler rod is the way to go - I have a kit from Jaycar Electronics that does a great job on these. https://www.outdoorking-forum.com.au/forum/ubbthreads.php/topics/86008/plastic-welder-butane-fuelled.html

That 'clip' is actually called a 'Tinnerman nut' - and no, it's not ex-factory - you'll have to work out why it's there.

Re the blade disc and catcher flap, powder coating is a major no-no! It gets damaged, water gets trapped underneath it, and away goes the corrosion process - on steroids, so to speak.

For a working mower, I'd just clean off the loose rust with a power wire brush, then brush on a 'fish oil' corrosion preventative, and let it dry. After all, have you ever seen a rusty fish? grin

Cheers,
Gadge
