Thanks Jim, Gil, Nick and Mike.

I will need to find an appropriate cord for the cordless one (Transitional?)

I really enjoyed the back and forth between Nick and Mike.

Thanks for the pictures of your 35 Nick.

13 J35s Mike.  Well done!

I had one other one which had converted to a gas burner which I traded or gave away.

We’ll have to ask Jan what his engine has since that has a decal…
Just to add to the confusion...it has a slotted pin Nick.

I would assume that your slightly younger un-slotted crankpin, is a result of running out of finished crankpins.
Especially since it seem rather long, compared to the one un-slotted pin i have here in my collection.
If he had a larger batch due for delivery, i can easily imagine that Jensen either decided to dig into a box holding semi-manufactured but fully usable parts, or swiftly made the pins needed, without spending time on the last machining operation,

This makes me almost want to collect Jenson now LOL!  Though I have had a hard enough time getting the Empires that I have, I don't think my OCD could take on the Jenson line ;-)

nice 35's you have Charlie. Jensen #35's are generally unappreciated like I think they should be.

Very nice, Charlie!

Why do you gotta point out all these differences making me want to collect more?? 😂

So what kind of crank pins do yours have? Slotted for screwdriver or no slot?

All the differences are exactly why I have thirteen 35s. 🤣🤣

I believe mine are mostly all slotted except for the very early ones.

Well that just makes it stranger being my non-slotted pin is on my brass tag…  :D

Found one here, pretty sure I have another elsewhere… this must be a large hub? I also noticed my crank pin is not slotted for a screwdriver where Charlie’s is.

That is definitely a large hub flywheel and could be transplanted directly to a model 5 or 25. That engine strikes me as unusual since I can’t remember ever seeing a later brass tag 35 with that flywheel. The ones I’ve seen are earlier with the Jensen decal and what I call the “herringbone” cord.

I assume it’s original as it’s very clean/unmolested looking other than needing a polish and light cleanup… I see the second one I posted has the herring bone cord.

Pretty sure I owned that engine at one point. Lol

Maybe I sold it to you or bought it from you??  :D  Pretty sure I sold it to Jan… @classixs is your memory better than mine?? :D

I sold it to you and then you sold it to Jan. I remember having a conversation about how that engine was really racking up the miles. 🤣🤣

Here’s my two brass tag 35s with small hub cast iron flywheels, one narrow and one wide. The only other one I’ve seen besides these two and Charlie’s, is an engine in a YouTube video.
The often overlooked 35 can be quite interesting when given a closer look.

Very nice line-up of 35s.

I love looking at all the heavy cast iron flywheel models.

Here’s one that I think went to Jan? I sold it after getting a Forgotten 35 when I was at a point where I thought one 35 was enough to own since the collection was getting too big… but now I’m back to a half a dozen or so 35’s… 😂

Nice lineup Charlie, didn’t know you had that early one! 😍

I know I have a couple heavy flywheel 35’s, but not sure if I have any with me… off to check now for Mike’s research to write his book on Jensen 😜

Very nice, Charlie!
The brass tag 35 with the small hub cast iron flywheel is quite rare by my observations. Seeing yours today, I have only ever seen four of these engines, but only two with the wider flywheel rim like yours. The other two have a narrow rim like the diecast flywheel.
I have two of these bras tag 35s with the small hub cast iron flywheel, one narrow and the other one is wider like yours, and I just got it yesterday! Lol
I’ll take some photos of my engines and post them a bit later.

I pulled out my three Jensen 35’s after watching Mike @Junkologist’s video the other day.  And I decided to clean up the worst of the three.

Before Pictures:

All I did was clean it up a bit.  The original safety valve is still in ICU.  And I need to find a whistle handle in my spare parts and replace the electric cord (which is missing). It runs on just a few psi.

Here are a few pictures after the clean-up:

I also made a YT short of it running:

Finally, here is a picture of all threee of my Jensen 35s:
