Roger on that Oil-Cap-removal test Grumpy - I'll get back to you sometime after the weather breaks enough up here to take the unit outside and give it a run...

Thanks for the crossed-fingers Chris. If this is anything like par for the course with Briggs, then like I said earlier - it's all a bit underwhelming for an owned-from-brand-new mower...

Gents, I had a 3rd or 4th-hand Classic-type 200-series a few years back, and I can't remember it having oil leaks anything even remotely like this one has. Mind you - from memory - I think the Oil Filler was a short-little, all-metal, screw-in affair, that screwed directly into the lower crankcase (so there were no O-Rings involved at the bottom, nor rubber seals up at the top under the lid...) Hmmm...

Anyway, we'll see where it all goes from here. Will get back to you when I can Grumpy.

Best Wishes and Thanks Again,
Mick.
