Looking to Buy a Monza/Chevy Jr H35 Tecumseh engine
Posted by: ral1963 ()
Date: August 03, 2022 05:54AM

If you have or know anyone who has a Tecumseh H35 engine out of a Rupp Monza or Chevy Jr, I need to purchase one for one on my karts.

I prefer an original H35 as originally installed by Rupp when built. It does not have to be complete or running, as it will be restored/rebuilt.

Thanks,

There are a total of eight with some saying "vintage" on the first page.

In all actuality, none of those are "correct" for what I am looking for. Like the Corvair engine code "RB" for a 140ph, I need a specific H35 Model and posted here looking for one from a Corvair guy who may have had a Monza/Chevy Jr at one time or came across parts for it.

There were probably 50 "models" with different setups of H53 used in everything from tillers, generators, pump, snowblowers, karts and mini-bikes. Each has a specific configuration of intake, exhaust, and throttle linkage.

There are lots of H35's out there, but I am on the hunt for a specific one....

I will also add that the current Ebay ones, although they are H35's...they are more modern version built in the later 70's and I need a version from the 60's.

Its funny how stuff from the early 80's is "vintage" now...

Hi Rick, I am also looking for a more correct motor for my Chevy Jr. It came with a modern OHV Tecumseh 5 HP, and I recently acquired a white H35 although I am not sure what it's original application was nor what year it is. It was $40 so I thought why not.

Can you post more details about what the correct H35 might look like so we know what to look for?

What would it take to convert a non-kart H35 to a more correct style?

This guy might be not too far from you:

Ryan,

I am away from the house for the day but will definitely help. The 1964-on H35 basic block and heads are basically the same, the only things that changed for various applications were the shroud, air filter setup, carb intake, and linkage. Of course, those that are really looking for exact, the serial plate has a date code like the Corvair engine code so you can really go down a rabbit hole looking for a correct year build.

I'll need to know the model of your kart to specify what intake style and exhaust setup.

Thanks Rick. I don't know what year or model I have. I tried looking for any stamped number per your other threads but haven't found anything yet. I am less concerned about the total perfect originality, but would like the engine to be more or less correct looking for the average person walking by.

Solid 1970-74, most likely 70-73 unless you can find serial numbers stamped into the outer left Floorplan about where your ankle/calf would be. On the inside of the body, sometimes the mold # used, they worker and the date build can still be read otherwise only the original engine serial # could be used to narrow down the exact year.

The good thing is all the late 68 to 74 engines were all configured the same and I can help you with some pictures of the intake and other small parts. The hardest part to locate if you don't already have it is the side mount gas tank.

That is cruel, Doug, really cruel! I've still got your RM block sitting in the garage.

Rick,
As a last resort, there are four Chevy Juniors that sold on Bring-A-Trailer. It might be worth your time to try to contact the buyers and discover if any of the sales involved extra parts.

The average person walking by could probably know or care less what engine it had. The body is what really matters and if it actually runs.

I was wondering if you were going to respond spinning smiley sticking its tongue out

I sold the other engine to a local member now that I don't need them.

Ryan, Tecumseh switched from white to "Silver gray" in the early 70's. Your H35 in most correct period look would be like these images.

Did they ever use the smaller 7 cu.in. H25 ?

All of the original factory literature and GM vintage pictures show the very 1st kart running a H35 to the last 1976 dated literature from Rupp selling off their old stock shows an H35.

The 3.5 HP engine was underpowered with the 40 body on the kart and is a reason why so many no longer have the original engine, most owners threw a 5-7 HP engine in and made it fun to drive.

The 60's Tecumseh burned alot of oil and with the body on, wasn't easy to check the oil levels, many were ran dry and toasted...and replaced...

I highly doubt (99.999% sure) any Rupp Monza or Chevy Jr ever left the Rupp facility with anything other than an H35 on it.

Now once it arrived at where it was being raffled or "sold" who is to say what happened even while it was brand new....

I will add that early 60's min-bikes normally go the H25's and the kart got the H35's. This was on their "fun" kids/young adult style offerings. Their "race" or performance stuff got bigger engines.

I went back for a quick scan of my "stuff" and found this 1970 ad...shows that for the "budget" D-300, it came with a H25, but the Chevy Jr was still offered with the H35.

The body of the Chevy Jr weighed nearly as much as the entire frame of the stock D-300.
