Marc,

I can try to rotate the starter.  Looks like there are extra holes. 

Need to assess the bolt pattern for the guides.  The drawing doesn't specify spacing, just bolt size.

I will call SEW once I measure my old H-70's bolt pattern.

Thanks all,

Chris

Marc, all,

You are correct - it is a paddle wheel Simplicity 724 model with the H-70 motor.  I did confirm a CCW rotation of the shaft which is on the left side (in operator position).

My dad (87) just hates parting with his old stuff.  I have to admit - it's a beast of a machine.  It (H70) threw a rod, and that was after I repaired it 2 years ago.  Makes me believe there was something else wrong.

The replacement Tecumseh motor's pull starter would face front, but it wouldn't be a problem since I could pull the starter rope outwards past the machines handles.

I believe I would need a spacer block, as the H70's shaft height is higher than the replacement's  - 4.125".  I'm going to remove the motor on my next visit, and get the measurements.  I did see the snow motor on the http://smallenginewarehouse.com site for $240.  That will work, I believe.

Marc - One thing that might be a problem - the machine's belt guides are bolted to the H-70's motor area near the output shaft.   Is this going to work with the new motor?  What did you do?

Thanks - great forum!

Not sure.  I'll have to take a look.  But  the pull starter on the Tecumseh 8 hp replacement will face the wrong way, making it awkward to start.

My dad's Simplicity 724 with the Tecumseh H70 bit the dust on Saturday. 

I've looked at replacing the engine with a B&S, but it appears the B&S output shaft turns in the wrong direction (CCW),  and the pull starter would be facing the front of the machine.  

The H70 is a 7.0 hp, 3/4" output shaft on the left of the machine when you are in position.

Any ideas?

Thanks!
