Chris, is that a new starter? I think you had starting woes before?
There are two types of flywheel ring gear (on a Mini anyway) the later pre engaged type don't mesh with the earlier inertia type 
Yes, and it does engage properly - but it is a tight fit against the firewall.
Oh and that's an interesting looking blanking plug in the dizzy drive hole
Are you still using the factory 'bullet' for the pressure releif valve behind your new adjuster? Some guys like to swap it for a ball bearing, 3/8 I think, out of a mini CV Joint!
Cheers! 
The plug in the distributor hole is just an expandable frost plug. I was thinking of making a vent with a filter to fit there, but maybe later.
And yes - good call, oh omniscient one in the practice of pommy potmetal persuits. Nuts and balls - no plugs. Bought three springs to find one that fit properly.
I need to have a little talk with the guys down at Area Rental in New Berlin, Wisconsin.
Picked up a rental cherry picker today. It was an absolute mess. I just spent three months building an engine in a clean environment, and I’m to install it with something that looks like it fell off of a garbage scow?
After I complained to the kid working the counter, he did me the courtesy of throwing a blanket down in the back of the Magnum.
Gee, thanks – wouldn't it have made more sense to just clean the thing up?
Which I did.

And at that time, I realized that there was no handle for the ram! Okay, I make a call to let them know I did not receive it, and they noted it on the contract. My floor jack handle worked fine, but that was just the beginning.
I’m raising the engine, and the ram starts leaking like an excited puppy. Good lord, does it have enough fluid the finish the project? They closed at noon, so my next phone call went straight to voicemail.

It did, but now my garage floor is a stinking mess, and I had to keep pumping the darned thing to keep it from slowly drifting into the engine bay. Under normal circumstances, this is a one man project, and in fact, when I originally pulled the engine when I got the car, I did it by hand. It wasn’t easy, and I won’t do it again, but I pity the SOB that winds up renting this piece of trash to try to install a big block Chevy into his pickup.
I have no intention of paying for its use – this was a joke, and a dangerous one at that.
BUT – it’s in.

Oh, and that’s Austin, our good luck road gnome. He spends most of his days sequestered in the trunk of the MGB, waiting to pose for photo ops. Kate has the pics, but he's been to St. Louis, Chicago, Door County, Toronto, and she’s got some great shots of him posing in the parking lot of an Upper Peninsula tourist trap, which I think was somewhere between Saul Ste Marie and Escanaba with a bunch of wacky vehicles. I’ll see if I can dig ‘em up – next month.
