Awesome. Do you have any pics of your motor mount. You got me thinking.:thumbsup:

 

[lawn-boy biker]

Lawn-Boy models "F", "V", and "E" work best.
Here ya go:

Man, that is awesome. I really like it. Is that a mower crank? Seems long. Again, hats off to you, I love it.

Is that a mower crank? Seems long.

Engine is 90% stock from an "off the shelf" DuraForce model "E" Lawn-Boy mower (as pictured above). Threaded end and short taper are for blade adapter and has since been cut off. ¼" keyway has been cut into crankshaft with a Dremel.

That is some kewl chit there! I love the sound of them two strokes thumping like that.

Question? do you think a torque a verter setup would work better? I have about 5 of these lawn boys laying behind the garage and would be fun to put a 2-stroke and a TC on my brothers fox fx200.

When you do a horizontal-to-vertical conversion like that, what do you do about the carb? I'm assuming you make an adaptor plate to compensate for the 90* engine rotation .... nice work on the cart, btw.

Probably. I have one, but mount would have to be re-worked to accept a TAV.

Adapter plate not necessary as I use a diaphragm carb. Original bowl carb is far too restrictive and places severe limits on mounting options. Engine will operate in any position.

That is some kewl chit there!

Again, hats off to you, I love it

nice work on the cart, btw

Thanx,thanx, and thanx!!!

Very Nice. I might come to Huntington and blow your doors off. Wait that thing does not have doors. I will race you for Pinks....hahahahahah

 

[Jay Wrix]

Any tips on making the plate?

 

[lawn-boy biker]

Any tips on making the plate?

Yup, a couple of things.
I used 5/16 thick 6061 t6 aluminum plate for upright and 6061 t6 aluminum equal leg structural angle 3" x 3" x 1/2" thick to support plate. Completed mount is then bolted together with 5/16 x 18 bolts and mounted to kart.

Got the twin thing goin'. Just the right hand power plant is operating until it is tweaked.
The same will be done on left engine.
Once I am confident of their "symmetrical power (???)", both will be powered up. Stay tuned!!!

Thanx.
Second engine (left) was tested this morning. Both are pretty much synchronized now.
Will attempt a full blown test tomorrow.
