My son in law fancies himself as a bit of an artist, I offered a few suggestions to help it along. I like the end results.

Very neat indeed sir.

Funny how different guys will see different things things.
By the way, anyone who hasn't seen the video of the tour of Marks museum, it's worth the time. Well done and informative. It reminded me I need to rib my dolmar buddy that they had to make em look like a Mac to sell any down under!!

There's very few things busier than having Mother nature as your boss.
As an old farmers wife once said, " it's a good life ,if you don't weaken."

Yes she's tough and unfair mother nature but soo rewarding too

Well I'll be a monkey's uncle.Congratulations Jethro! I guess I don't have to ask what you've been up to lately,Lol.You'll find out how much work it is to prune all those fruit & nut trees.Great wood to heat with too.I'll be 65 in June & I keep on planting trees myself.Seems the wildlife here gets to the fruits before I can.I've found that deer are no more than rats with hooves.

Hahaha rats with hooves.

Yeah a huge amount of work Ed absolutely. 1 handy thing there is a lady who runs a horticulture course in a town 10 min away and needs trees for her and students to prune

I see it too

 

[Syncop8r]

I see it too

Now you can't unsee it...

Hang on tight, I take big bites.

It's not a chainsaw yet, but it's almost there.
My first legitimate kart engine came in the mail a few days ago.
I took apart a 1-40 for donor pieces, though I couldn't bring myself to cut up the pistol grip/carburetor box. It still has the bead chain that keeps the carb tuning cover fron getting lost, which I've never seen completely intact. So I ordered one off of the internet along with some clutch pieces.
The engine has been freshly rebuilt. Can't remember exactly how big the bore is off of the top of my head other than it's got plenty of meat left. I believe all ports & port timing are stock as well which is nice.
The thing has an awful lot of compression! With the rings being new I'm sure it will only increase! Dunno what size head gasket it's sporting other than it looking much thinner than the typical saw setup. Hopefully it's not so much that things get broken!
Today I might try to find a stack & a filter for the bdc22. I'd make one but my tig torch hose has become very leaky all of the sudden..
I don't have pics on my phone, but I bought a 2nd engine just yesterday. It's an mc92 that I'm pretty sure, almost positive has never been run. While they're dirty & tattered, it still has it's original box, plastic bag, literature, new plug, & exhaust gasket!
It was the ugly twin of the two engines the seller had. The nice one looked to be positively spotless, still in it's plastic bag & all. Some of you likely saw it on ebay, maybe one of you owns it now!
I need to pop off the crankcase side so that I can properly secure the rear handle. That's about the most labor intensive part out of everything that goes into assembling one of these old things it seems.

I believe you can rotate that starter 45 degrees or so CCW, you will find it make it much easier to pull the starter.



I modified the airbox to fit over the manifold and added a spacer in the handle.





Since that one is a Super series engine I had to mount a fuel tank where I could.

I believe you are absolutely right!

For some reason I assumed the other three holes were just for show. I'd seen saws with the starter rope oriented for the pistol grip drop start. Now I know that all 6 holes are indeed functional lol.

This should be right functional as well once I clean what I'm assuming are the remnants of the factory lubricant. Looks like rust but wipes away like some sort of cosmoline like substance.
Do you know if & if so, what was used for assembly lube & or rust inhibitors? don't think the engine has ever run.



I should probably replace the seals as well. Although they still feel pliable.

By the way.
If my spelling seems atrocious, my new phone, an s22 note, has the spelling of a middle school dropout. It misspells correctly spelled words & changes others flat-out. It tried to change "proceed" to "proced"... changed "mail" to "male"..... Capitalizes all kinds of random words as well.
If you turn the predictive typingoff, it's a struggle to compose a sentence without an error in almost every word.
I've learned that every word underlined in black can be tapped, up pops a misspelled version of it. Am I taking crazy pills or are they trying hard to make people dumber & angrier?
I should consider proofreading.

That's OK, if we can understand Jethro we can work out what you're trying to say.

Well, my curiosity got the better of me, so I got up & loosened some allen bolts.

It's definitely been run.....
Oh well, not really important.
The bore is still stock @ 2.165". However, it sustained some scoring somewhere along the line. Looks like all of the smaller stuff has cross hatching lines over the score marks. The largest mark is clean. The largest is also the only one that I can feel with a fingernail. However, a metal point doesn't catch on it or any of the smaller stuff.
It's interesting how the wall above the exhaust port is the cleanest.
I don't know what kind of a life a kart engine lives. In that whether not what appears to be very lightly used is indeed very lightly used.
I'm used to chainsaws, where it's usually pretty easy to tell how much work had been done. I figured that chain rash would be a good indicator, but there is none to be found.
In any case, it's a prime candidate for a working class kartsaw. Even if someone blew it up & tried to pass a hone through followed by a new piston.
Or maybe it ate some road dirt with just a few hours on it.
I swear that I'm seeing what looks like oily sawdust fines all over it. I was assuming it to be decades of storage dust, but now that I know its been run, maybe it's already been a chainsaw.

I'm very impressed with those pictures of the bore. Interesting evidence so far. It could be saw dust from being in a saw guys shed. You'll find saw dust/chips on or in pretty much everything I own.

I kart gets an absolute thrashing to end all thrashings. It very well could of done a 5 or 10 hour stint before a rebuild and then perhaps they put something else in and chucked it on the shelf and it never got used again. A kart engine 10 hours could be a saws 1000 and would explain why its so mint on the outside.

Never really will know but what we do is that thing will rip a saw chain along very nicely indeed
