Hey, back when I worked on fast movers everything was titanium...I hated that crap... when it breaks, and it does, it's dam near impossible to get out... diamond tip drill bits...stuff like that...it kinda breaks like glass.

Anyway...

Good steel shouldn't attract a magnet either...if it rusts or pulls with a magnet then it has a high iron content making it a poor quality steel...so there you go...I know in the scheme of yard gokarting it doesn't matter but in other circles it makes all the difference in the world.

Thanks for all your help 950speed
Whatcha talkin bout willis?...good steel doesnt rust? So only 300 series SS are good steel (and a few other exotics), barely magnetic at molecular level, a basic magnet won't stick.
So 1045, 4140, 4150, S7, A2, A36..etc are not good? (Many more types) Different metals for different applications, we use 17-4 SS for aero parts and its magnetic
So your broad stroke of the brush could be confusing to readers

OP sorry for hyjack, I apologize

Bahahahahahahaha....

Put those numbers down! I just like harassing people that call sh!tty gas tank stampings made out of steel! You obviously know what I'm talking about or you wouldn't have called me out on it!

I call it sheet metal. Actually one of the few things I prefer made from something other than metal...at least low quality metal anyway. As soon as rust sets in it forever more ruins your day by stopping up the carb.

There's a variety of places to get parts. These other guys probably know the answer to that way better than me so let them chime in.

I know of a few places, but as you can see I'm somewhat jaded but ARC racing parts comes to mind.

Oh yea, I just now got some gas for my little air cooled sweeties!

By the way, we don't want anything magnetic(ferrous) around our compasses or navigational devices or our flux valve that might throw off our magnetic navigational devices...of course GPS don't care.

You funny guy. For a minute there I was going to just say, "well, he's a wrench turner not a metallurgist"

So let's go your route and avoid the boring details. We'll just call the gas tank metal, no need to be more specific. Going further, we won't call aluminum, aluminum. Lead is not lead, and gold is not gold. Those are just metals. Kosher?

I guess I have an affinity for ferrous metal. Darn near everything I like rusts. Pfffft.

I like lead...it don't rust, aluminum don't either.

Rusty gas tanks just **** me off that's all. Rust in general ****es me off.

I even cast my own bullets occasionally. And my favorite molds are made from brass...not iron because it RUSTS!!! And brass drops a better looking bullet...just gotta stay on your toes with it!

So what will we call your head, meathead or blockhead or bonehead? Or something more fitting? Spunkhead?

Arrrrrrggggg I didn't get any work done on the Briggs today!

Maybe I can toss the carb in the ultrasonic cleaner.

No no, I'm the spunkhead!
For everyone else it's just a "head".

You talking about your mini bike build?

No, not really on purpose any more.
There was a period I didnt have any tarps... so it sat for a bit till I got a few... Now that I have a more even controlled amount of "patina"(I really hate that word.....its rust), itll wont be too long before I clear it to lock it in...
I do go over it every couple of months to knock off any rust forming, and dose it with WD40. a good coat helps for a bit...
Its got an even weathered bare metal finish....
But spotting occurs when ever I go to a show and it rains.....

Some more updates on the Briggs 9.50 series.

I had left you guys with removing the head.

The broken tab I have found is where an optional dipstick would have mounted to for support and the big hole beside it would be opened up.

The engine is now completely disassembled. I'm waiting on gaskets to put it back together and still trying to decide if I want to build it up or just put it back stock and shelve it for later.

Oh, a quick glance at the cylinder walls and you can still see some of the original hone marks where the piston rides. Also some obvious water stains and some lines because the PO didn't have an air filter installed. None of the issues stated where measureable. I couldn't even snag a fingernail on any of the lines. I'm just gonna bump it real quick with a hone and some 220 stones and see how it comes out. If I decide to build it up I'll get way more serious with it. But for now I think I want it running and off my work table.

At any rate I'm going to have it running on video for everyone to see.

Finally got around to honing the bore. Medical reasons and the insane heat has kept me from my projects. I just lightly honed it. I didn't want to do much to it as I am putting the same piston and rings back in.

Lightly oiled the bore and the bearing to hold me over until I thread the governor shaft hole and the oil sensor hole. When that is done I'll finish up with a final scrub down of the crankcase then start putting it back together.

Got out and tinkered with this thing again today. Started putting it back together. Tapped and installed the hose fittings in the empty spots where the oil sensor wires and gov arm went through the block. I hate npt fittings. Cleaned up the case and put some of the innards back in.

Stopped because I was hurting too bad.

More progress, starting to look like an engine again, maybe motivation will strike me soon...or I'll get some spare time...

Ok!

So today...tonight...I got this engine finally put back together. I had a few minor hurdles to jump but not too bad.

I had ordered several gasket kits from GPS several months back and the head gasket didn't wanna fit over one of the alignment pins right so I had to take a drill bit and open it up. Can't remember what I ordered but it was a real thin black copper gasket I think. But anyway, it's not as thick as the old one was.

Everything was going back together really well except I didn't have the original recoil starter for it so I grabbed one off one of my stand by predators just to find that the dimensions aren't quite the same...I got it to work nonetheless.

Then there was the carbonator...yup... that's what I said...any sane individual would have tossed it in the dumpster...but no, not me...

I had to give this piece of junk a go...

So, I'll leave you all wondering what happened and with that pic until my next update tomorrow!
