Case acid cleaned ?? Never heard of using acid on a case to clean it. Parts of case look painted note oil plugs. and why not replate bolts and fix rusty cooling tin straps. Don’t mean to pick apart someone’s build just being honest.

Make sure your crank pulley is proper size to match the Carrera fan for a 710 belt
You didn’t trim the cylinder dividers for additional cooling.

acid cleaned.Mmmm.That oil plug is steel.looks painted to me,should be zinc pasivated.

The replacement oil line connectors turn up this way .. and it’s been done before the to spin the fan faster for more cooling. I think using an SC crank pulley and 725 belt.

Were I to consider buying this (and I am not in the market), I'd not view the bling or its lack as being very important - I can wire brush the exposed slightly rusted studs. Replating has never been on my agenda for my own motors. But all that paint wouldn't be a special plus for me. I, too, wonder why the cooling tin didn't have the modification Anderson pointed out in his first book long ago, but I wouldn't care about the rusty tin spring holders - they will never rust through or lose their needed tension, and you can't see them.

I do wonder why an engine which looks like it comes with carbs doesn't have the air injector holes plugged, though that is easy and not expensive to do. Is that because some purchaser might be in a state which requires the air injection on this motor? Can you even get that stuff any more?My concern with the scavenge pump output fitting is with tightening the oil line fitting with the return tube in place. Is there a special tool which works better than ordinary wrenches in this tight space?

My understanding is that spiffing up a mag case isn't very effective, as it quickly re-oxides or something back to its usual dull color? Just sort of makes you wonder. But I am a function over looks kind of guy.
