Author Topic: I need a trip down memory lane!!! Help!! (Read 2200 times)

When I was a senior in high school....I kept dropping by a little hobby shop in Tillamook Oregon...(the only one in town) that was located in an old make shift hobby shop in a garage near main street.
He had in the window....a brand new OS MAX 35 TWIN EXHAUST engine...that I just had to have for my old Kenhi Cougar.
What an intesting design...and the only engines that I had been using before that were two old Forster 29's that I had ordered from AHC catalogs so you can imagine just how blown away I was with this new powerful little easy starting and smooth running engine.

I NEED A TRIP DOWN MEMORY LANE? I have tried to find a photo or an old story about that engine without success?
Anyone around that can give me my "OS 35 TWIN EXHAUST FIX" for today?

uhhh? I just found a .29 version! Guess my memory lane was a bit shrouded huh? It appears that it was a .29? I would have bet on a stack of Bibles and old MAN issues that my engine was a .35? So much for reality....huh?

Hi, Don - as I recall, it was a .36, not a .35 but I may be wrong.

I have some of each and I remember that one of them, the .36 I believe, had an oval boss just below the venturi with "Atwood" stamped in it.

Pretty sure Bill Atwood had something to do with it, either design or import.

I've had mine for years but never tried running it.

Thanks Bob!....
I "think I remember" that it was indeed larger than my old Foster .29 so it sounds like it must have been a .36?
Most of all I do remember just how much of an improvement it made in my old Kenhi model.
Tillamook Oregon...used to have some pretty weird winds that alway came up in the afternoons...so we did our flying early in the days..at either the Fairgrounds or at Diamond Lumber at the Blimp base south of town.

HI BUD;

I only did this cause it is for you. Bob Z. is correct it is an OS .36 Twin Stack. Circa 1953. It can be seen here:

I am sure you will know what to do next.

I bought a new twin stack .29..........it pulled about like a worn out O & R .29....no, come to think of it, the worn out O & R....was stronger....what a dissapointment that engine was.......my next venture into the world of Jap junk was a OS .80, again bought new to replace a well worn Fox .59 on an original German Telemaster.....another big dissapointment, the OS .80 pulled no better than the Fox .59, so I traded it to a suc.......errrr, Buddy for a Fox .74 and laughed every time that I flew that ol airplane....:-)

BarePhil....

Gee, how old are you?

Remember this was waaaaaaay back in 1956 or so....I had even forgotten that it was an old OS .36 and not a .29
Again...remember few engines in those days..and even today are not quite created equal..plus as you must already know that so many factors can make even the best engine run ratty like your old O & R's n' OS twin port .29? Plugs...fuels...tank arrangements made just a difference on those old engines, not to add in the problems of head gaskets and backplates n' nasty needle valves?
Also compared to my old Forster 29s...In that old Kenhi and later in my Kenhi Panther...that new OS .36 really made a HUGE difference. THAT I CAN REMEMBER!

Here is another photo of that old .36

Phil Bare · « **Reply #6 on:** April 21, 2007, 06:14:57 PM »

LOL, almost as old as you Shultzie...:-)

and yeah, I do know all the varibles that affect an engines run........and my old O & R .29 was just slap worn out...had ta squirt a lil axle grease in the exhaust port in order to get nuff pression for it to even start...:-) and I later figgered out why that twin stack OS.29 didn,t make as much power as a Cameron .19.......with those two stacks, the zaust didn,t have time ta figger out which a way to go, sos it just kept burnin the same stuff over and over...........didn,t have a chance....
and as for Forster .29s......I got 2 G.29 RIs and they both make good power...but I also have a GHQ that,ll turn a 16 x 4 at 17,000 Rs...

Shultzie · « **Reply #7 on:** April 21, 2007, 07:09:22 PM »

Ahhh yes...
A Cameron 19! What a beautifully made engine that was waaaaay ahead of its time, Huh?

Ok! Phil and Bill!! Confession time.

Any idea when AHC starting advertising the little Spitzy .O49s?

Yep, the Camerons were nice engines, easy to handle and get good results from, Do you remember the Rodzy cars??

I dunno when AHC started selling the Spitzy, but it had to be in the very early 50s??
My very first new engine was a K & B Torpedo .09 that Dad got me for a christmas present the year that I was in the 4th grade.....I must confess, I did have 2 older brothers that (helped) me with my modeling endevors though..

The older brother was a superb builder and the next was just an all round great brother, he also had a Comet Sabre 44 that we all (flew).......later in life, when he was 45 years old, he got his pilots ticket, called me and wanted me to find him an airplane, (low buck 4 seater that he could do some cross country in) I found and bought a run out TriPacer and flew it home, took the wings off, got it in my shop and totaly rebuilt it for him........his commitment for that ol TriPop kept him going in his lessons and after his check ride, there were many great trips from Ohio, where he lived, to NC where I live....oh, and when ever that ol triPop was at a fly in or show, the announcers raves always made him light up with pride in his airplane......Sorry to say, lost him some years ago to cancer....

Shultzie, is that your milkstool? looks good. I wonder how many on here have their own plane, I know of one other besides myself.

Bob Zambelli · « **Reply #15 on:** April 26, 2007, 05:43:28 AM »

MILKSTOOL!!!!!!

I like that. It was my very first airplane ride.

Now it's my Piper Warrior.

I don,t own a airplane now, but over the years, I have owned serveral: 38 Taylorcraft BF 65, 41 Taylorcraft BL 65, 46 Taylorcraft BC12D, 56 Piper PA22,
57 Piper PA22, 49 Piper Clipper, Hovey Whing Ding UL, and a Stolp Star duster 2....

I lost my medical (or became unable to pass it) in 2001, sooooooooooo...:-(

Schultzie, to your Reply #9...

My first engine was also the one-hung-low Spitzy, around 1950 or so, In Brooklyn, NY.

HOW..ev..err - it turned counterclockwise, if I recall. Someone flip the negative, er, image, er, whatever??

And no one else caught that so far?

Still have a few visible scars from an early .049 Wasp, btw. Scar comparisons among us tend to get like the night-aboard-the-ORCA scene from JAWS, no?

Gads...U are GOOD! I "snipped" that photo...and I agree that either the slide or neg. was reversed in printing.
also the needle valve is another clue?

No...its not my "Milkstool" but one of my old Boeing bud's rebuilt one at a hanger about a mile from my home. He was always kidnappin' me and my tools to help him restore that beautiful old tri-pizzer of his. I did fly often with him...AT NIGHT while he was working on his license.
I OFTEN THANK THE GOOD LORD ABOVE...that Mel was such a good and fast learner. If any one has ever flown in and out of the Auburn Wa. airstrip at night...can understand when I say that we had some very very interesting and entertaining landings and almost sat it down in the Diary Queen parking lot that is located across the road at the very end of the south run way.

Fog sets in early in the eve. here in the NW and the bright lights of the Diary Queen was an excellent "target."

I am going to give myself away here. My favorite engine in 1948 was an Ohlson 33 front rotor on glow. It was the only engine that would work on a Demeco Sportwing and have a decent lenght of an engine run on the small tank that you had to put in it. The engine ran really good and launched me into a class by myself so I thought. It sure beat the old Rodgers 29 I had on ignition. Boy Did I like learning all that stuff.
