Got one of the tractors on my dream list!

[CasualObserver 3,411]

Nice looking engine Jeff! Can you do me a favor and tell me what the size is of that carb? (the little number cast inside intake side behind the choke plate?)

[WHC-125 4]

Nice find Jeff cant wait to see it dropped in the 35 :notworthy:

[whfan74 2,071]

That sure is a beauty and I am hoping that I will be lucky enough to find such a solid tractor like that some day.

Really looking forward to you progress on this one. You do great work! :thumbs:

I finally found a K90 for the RJ35. It's in incredible condition. Doesn't look like it has been run for to many hours. Could even have been rebuilt and never used. I have a Morse-Fairbanks pull start for it. I'd love to find a Schnacke pull starter though . Anyone have one for sale .

I'd be interested in your Fairbanks, should you want to sell it.

[wallfish 18,076]

NICE!

That's the K90 carb and bowl I was talking about at the meet and greet. I see your choke lever is hitting the air cleaner. Make sure it can open all the way before tuning it. Do you have to tap threads into the exhaust port?

Jason, the 2 I have are 18s if that helps you any

If you do need a different throttle lever I will trade you for the right one.

Thanks John... I was asking because I have an old Carter N that looks just like that in a box in the garage... round bowl and all. Came from my dad's pile of old engine parts... and I had no idea what it goes to. Figured it was from a mini-bike or something... just never looked into it. Jeff said his number is 13... pretty sure that's what mine is too.

What's supposed to be on the K-90? a 13 or an 18? :notworthy:

Mine are on K90s but maybe I should put my glasses on and check those #s again. Pretty sure it's 18 though.

Are you sure it's actually a K-90? :notworthy:

[fireman 1,022]

OK I'll bite! What makes you think it's not a K90?

[wallfish 18,076]

He might be looking at the plug wire.

Original K90 would not have the boot on it and the wire looks new. The Bendix coil in a K90 has the wire permanently attached to it and can not be changed. A K91 coil is different and the wire is a separate part and can be changed. It appears like you might have the K91 coil since those Bendix coils didn

[TT-(Moderator) 1,162]

Here's what caught my eye:

Although it could have been changed, the cooling fins on the cylinder head are parallel with the crankshaft. A K-90 head should have angled or curved fins.

The blower housing has the hole on the side for the momentary kill switch. I have only ever seen that on K-91 engines - and very few of them.

The flywheel does look like the newer type with the built-in magnet for the ignition instead of the magnet rotor and separate flywheel, but once again..... that all could have been changed.

I am not saying that this this engine can't be a K-90, but it just seems to have more K-91 traits. I just thought I'd ask. :notworthy:

[TT-(Moderator) 1,162]

Thought I'd add this - even though I'm not 100% sure on it - but supposedly the "early" 1955 models did not have the exhaust pipe running to the front with the muffler on the end. Because the RJ was derived from the two-wheel walk-behind, the first "conversions" still had the muffler bolted to the block just like the one on Jeff's engine.

(not sure if it was exactly the same muffler with the louvered outlet or if they were the perforated round holes outlet type though)

I'm sure that after the owners of the early '55 models saw the revised forward-exit exhaust on the later models, they probably added it it to some of the early tractors in order to keep their pants from catching on fire. :notworthy:

[wallfish 18,076]

AH HA!

The head fins on my K90s are angled and the K91s are straight/parallel with the crankshaft, never noticed that before. I was curious about that hole in the blower housing, none of my engines have that.

[fireman 1,022]

Here's page 2 of a Kohler K90 Brochure I found a few years ago. If you look at the drawing in the lower left corner, the fins are parrallel with the crankshaft. The guy I got this from got it from a family friend who was the original owner. He said that all the parts are original.

All I know is that it is going on the 1955 RJ35 (or is it a 56 ), and it will look like it's supposed to unless you take out your microscope, and I will enjoy it just the same. Maybe one day a (TRUE) K90 or Clinton 1200 will find its way into my hands and then I will install it but until then...........................

The only thing I learned about the k series to the k1 series is that the mounting plates were changed so you could bolt a bigger motor on in place of a smaller motor using the same hole pattern. The k series (without the 1) were different pattern sizes. They went to the k1 series in 1959.

BTW-how do you keep stepping in chit like that?? Nice score on the tractor and the motor. Too bad you didn't have it for show and tell a week earlier.

I too also hate it when a seller playes games. I lost two tractors this year because of that. :thumbs:

My original RJ-58 has a K-91T. :thumbs:

John,

Sent you a PM. You'll understand when you read it

Guys,

I think unless we find someone who was there back then we'll never know for sure. I think there were a lot of variables. Just like the early Ponds (no two are alike), I think there may have been changes made through-out the model years. I have done a ton of research on the K90 and K91 and really can't find much except for the manuals and some chat on other forums about them. The Kohler site has nothing on the K90. I saw in a post on another site that Tim Lapree is probably the most knowledable guy there is when it comes to the early Kohlers (and Wheel Horse ). I am going to contact him and see what info I can get from him.

Looks like a nice tractor you have there,I only have one roundnose but that will change soon,Rick

[Coadster32 793]

Hey Jim (linen Beige), hope I didn'y come off to you like a snot. Sorry if I did. I stumbled on that RS post on google and was like..

Rick-looking at the picture, I don't see room for a round hood. However, if you have that many already, I'm sure you can make room for at least one more

You look like you're giving Hammerhead a run at quanity.
