Here's my self-promotion, silentgreyfellow:

If I needed to self-promote, I certainly wouldn't be turning away new accounts.

And you are not an established account, are you?

PS: Did I ask too many questions, Folks?
Thanks to those who replied courteously. Its about old motorcycles, not ragging egos.

What have you contributed to vintage motorcycling?

Tom, your around here a lot lately? You get thrown off a couple more forums? Bob

Hey, everyone needs a safe place to hang out. Some people may have exhausted their options, but if there's a personal problem, the solution is easy- just don't read it! Nobody forces anyone to read the posts of another member. Take it or leave it, like it or not. If it's too (fill in the blank) ____________ , then just hit the BACK button, or better yet, the big X. Problem solved.

Gentleman ! How about these pics of what's supposed to be a 1911 twin...?

It's pretty, Steve!

But I need more resolution to learn anything.
(And anything that "restored" makes me scratch my chin anyway.)

Back to "automatic":

"Pravg Schebler" was a Euro website several years ago with great information, although I can no longer find it. (Doh! Found it: http://www.geocities.ws/pravgeusau/schebler.htm)

It was one of the first to prescribe a modern material such as Teflon to replace the leather airvalve seal.

It refers to 'automatic' with "The Schebler model "H" carburettor was one of the first so-called "automatic carburettors", allowing single cable control, for motorcycles."

Tom, thanks for sharing good information. The pics i posted, i got off internet, were the best ones i could find; when available would download original looking examples instead of restored. my hope is fellow members will share pictures and information to build on my meager start.

when it comes to anything but a '27 model, i have no clue what i'm looking for or at !

and i don't know much about '27 models either ! mine i built with my raw know-how, help from fellows like you and researching every bit of original information and pictures of unmolested originals i could find. never seen a 27 in the flesh, so i'm sure mine has some incorrect stuff on it, not withstanding repro parts when i couldn't find original parts.

As most of us realize, Steve,...

All of our projects are only a work in progress, and may only "finish" when we do.

That's just another reason why an online roster to follow such progress would benefit not only ourselves as enthusiasts, and our posterity, but vintage motorcycling overall.

Automatic carburation and automatic carburetor are two different things and function quite differently although with somewhat similar end results.

Its obvious Folks!

Two letters are different.

Let's get back to the Steve's original topic, and something interesting.

This illustration is shows engines from 1910. I say that because the Merkel motor is a 1910 because it has the external mechanical oil pump on the outside of the cam/gear cover. 1911 used a throttle controlled oil dripper. So, I'm making a speculative leap of assumption and am saying that this trade magazine was showing a 1910 Harley-Davidson twin. Now, that could mean that the illustration was created in late 1910 from a trade show where H-D was introducing th3 1911 twin. Regardless, the Merkel twin is a 1910 for what that's worth

Great pic Eric!

But photobucket phuckets with me if I try to view it any more closely, or save it.

Its so easy to save to this forum direct!

When you bring up the box to post your reply, look below it for a 'button' that says: Manage Attachments.
Click on it, and a second browser tab appears. Somewhere in small print among all the bells and whistles it will say: Add Files.
Click on that, and then look in the box that pops up for Basic Uploader.

Clicking on that will change that box to say Browse.
Clicking on that lets you pick your picture from your computer. Then click Upload.

Click Done at the bottom when you are done, and it will close that tab, but the attachment will be listed on the first tab where you compose your text.

Its way too many hoops to jump through, but its better than an expensive external host that will make you jump through its own hoops, and hold your photos hostage someday.

Your browser may vary.

Eric, did the Flying Merkle have an actual oil pump that actually moved oil or was it a "drip regulator" seen on later Harley's ? On the 1910 Harley, how was oil flow controlled from the tank ?

[exeric]

The 1910 Merkel had a mechanical oil pump that was a clock-work affair with pivot arms, springs, cams, and escapements. Just because you can make something work doesn't mean it's a good design In function, the Merkel mechanical pump dribbled oil on the timing gears, but was not a pressurized device to get oil into the crank shafts. I had a 1910 Merkel and of course, all of that mechanical stuff was shot. The 1911 used the miracle of gravity, and natural fluid dynamics to get oil to the motor. . . Worked like a dream. The Harley of that era also used an oil dripper, and the drip was controlled by a needle valve, and was viewable in the sight glass of the needle/seat fitting. I believe the H-D drip was controlled by a knurled knob on top of the tank. The knurls corresponded with a spring loaded detent so you could select your d.p.m. (drips per minute).
