Wanted Lawn-Boy/Trade 196cc Clone

[ironman]

5024 is 1977 model 'D 433' engine and there is no easy way (that I know of) of setting up exhaust pipe/muffler. You will see what I mean when disassembled.
Same thing for 7261 (1972) and 7263 (1974). Both of these are 'D 600' engines.
All the above are 3.5 hp.
Unidentified mowers are 'F' engines and can possibly be used. PTO's have to be examined which would require removing engines from mower housing. These are 4.5 hp.

o my there is no way to put a exhuast on these motors this is a problem for sure because man its going to be very loud.started on one of the motors today got it off the mower and setting it up on a stand will post picture later got a few ? already

I did mount and run the 'D' engine (5024, 7261, 7263) but never used it because of exhaust problem.
Check out the unidentified engines first as these appear to be the most promising because they have threaded exhaust holes.
I will post pics of usable engine blocks this evening. Usable engines are model 'F's', 'V's' and 'E's'.
Your 2 unidentified engines are 'F' engines and show the most promise.
Hopefully they do not have auxiliary pto for transmission.

Hello,
I was diverted here from a lawnmower site after seeing russ's kart. I was wondering if you tore that commercial lawn boy apart? It would be a pain to use that motor potentially due to the clutch setup, I would think. Any chance you would sell the motor & handle to me? I'm in Wi so you'd have to ship. I could swap you a duraforce motor as well. They are everywhere around these parts. I also have numerous f engines as well. Let me know. Sorry to intrude like this on my first post. Thanks. -Dave

 

[ironman]

well send a picture sounds good so tell me what kind of trade you wanting to make im open to motors cash what ever just let me know.

Why cant an exhaust be mounted? I want pics, maybe my afro engineering skills will go to work.

That's what I want to know. The only reason I can think of that you couldn't mount an exhaust pipe to it easily would be that there is nowhere to screw a flange or it's just a hole that can't be threaded.

 

[Russ2251]

Yes to both.
Engine muffler is mounted to underside of mower housing.
When engine is bolted to mower housing, it meets muffler flange with a gasket sandwiched in between.
First pic is of exhaust port.
Second pic is completed prototype with 'D' engine. This was never tested. A couple of weeks later I came across an 'F' engine (freebie) which is more user friendly.
Pics were taken 2 years ago.

I think we have an LB collector in our midst.

"I see!" Said the blind man as he picked up his hammer and saw.

 

[Russ2251]

Some guy just offered me $1200 for my kart. That would be about a $400 profit.
I'm considering it. What a country!!!

 

[kibble]

HOLY CRAP! Are you willing to let go of your 2 cycle baby though?

 

[Russ2251]

He wants it as is, DuraForce and all. I don't know what to do at this point.
It is a 'one off, one of a kind original' and I'm thinkin' it's worth more than his offer.
I could use a new plasma tv.

You sure its not a scam there russ? That's an awfull lotta money for it.

 

[Russ2251]

No scam. I've known him several years.

 

[gocartkid]

Well if you do sell it then take careful measurements and lots of pics if you want to re-create it later.

 

[Russ2251]

Not a Problem. Next kart will be better. Maybe a Toro GTS mower engine (Suzuki) and yes it would be a 2 cycle converted vertical shaft.
A minibike may be on the menu as well.

 

[ironman]

after hours and hours of searching russ you are the only one that has a lawnboy setup nothing on the web ebay youtube or any other chat sight.if you can make that from one than we need to go in business

 

[ironman]

first picture as you can see no bolt holes for the exhaust

second picture this motor is from the utility lawn boy it has the bolt holes

motor mount plate doesn't look like it will be that bad on it.

 

[Russ2251]

You ain't seen nothin' yet. Soon I will post pics of Ryobi powered bicycle. Not fast but turns a lot of heads, even before I start it.
