Left side spindle engine

[Sam W]

Where can i find an engine with the spindle on the left instead of the right? thanks.

approx. 2.5 - 3.5 hp. cheap used or new

 

[dpaxson]

what do you mean? just flip the engine around. if that makes it spin the wrong way, use a jack shaft.

 

[Kaptain Krunch]

Or get a 2 stroke.

Sounds like you need a good chainsaw motor to me. Look for 50cc two cycles.

Most all of our kart engines have the PTO (the engines clutch shaft) on the left. If you want the opposite of normal, that'd actualy be a Right hand drive engine. Anytime your designating the right/left side of a vehicle, the method mechanics commonly use is from the perspective of sitting in the drivers seat.

Clinton (among others) made them for a few years and are really tough to come by now.
These guys make 'em but are much bigger than what you want:
United States Motor Power

Most Yamaha KT100 kart engines are setup for right hand drive, but this model can be switched around to drive off either side.

I was kinda wondering why your project needs an engine with a non-standard drive side?

i found a pocket bike frame for free so im gonna get an engine and build it.

so the rear wheel has a sprocket on the left side (looking at it from the front). i didnt want to mess with jackshafts but i guess thats what i will end up doing

just get a two stroke, they can be run in either direction as long as you can start them in that direction (modified recoil).

SERIOUS?!

im looking to get a cheepish $70 - $130 pocket bike 2 stroke.

can u hook me up with a couple links? like one that has a way to start them both ways? thanks

Probably won't run at all. Timing will be way off to begin with. No CDI pack that I own will fire in reversed direction.

Why would the timing be off? direction should not effect ignition timing at all. I have never done this on an engine with a CDI so i cant say anything about that, not sure how it would be affected by the direction of the crank though.

 

[modelengineer]

Even if it's just a set of points the timing would be some degrees BTDC, so spinning it backwards would make it ATDC. It might still run, but it wouldn't run very well.

Also, CDI uses coil's too.

Oops, didnt even thing of BTDC/ATDC, but i have done this before with some small weed eaters/chainsaws, performance is hard to tell on a bench though...oh well

I realize CDI ignitions use coils too, but they mounted directly by the flywheel like on small industrial engines, i'm arent just not sure what there called, transistorized magneto maybe?

 

[Russ2251]

Agreed.
In my case, CDI uses two coils. Start and Run.
Start coil works below 800 RPM is set at 5° btdc for ease of starting. Run coil kicks in after 800 RPM and advances spark to 28° btdc. I'm working on a version of this which (hopefully) will be externally adjustable.
Requires some (not too exotic) electronics.

 

[freakboy]

wow that sounds like a awsome idea..

Does instaling the rear wheel (or sprocket) swapped around the other way seem like a realistic mod?

 

[honda02]

Yeah, take off the rear axle and see if the gear is easily removed. Or just flip the wheel around. What kind of brakes does it have on the rear?

 

[Kenny_McCormic]

Put a KT100 on it!

 

[Sam W]

uh i cant switch the wheel around for 2 reasons.

1. The sprocket is a rachet so it will just spin the sprocket

2. the frame gets in the way of the chain on the right side
