Craftsman 10/32 Murray HM100 repower options

I have a 3 stage craftsman 10-32 snowblower with a solid HM100 with a bad ignition that I have been unable to fix. I am seriously considering repowering it as I need a strong snowblower for a large driveway. I am looking at a 13hp Ironton engine for 220$. I really would like to have an electric start but all of the engines I have seen use a 12v system so it doesn't seem practical.

Should one of these 1" Ironton or Predator engines be a painless swap?

The HM100 lost spark from sitting for the summer but thats for another thread.

Is your engine a single PTO or does it have a dual PTO? The second PTO runs off the camshaft and runs in the oposite direction as the main PTO. If it is a single PTO then a Predator 420CC 13 hp engine or that Ironton 13hp would work real well and you will see a definite improvement in performance especially if you install an impeller kit. A small ATV battery and tray can be installed in the back of the tractor to start your engine if equipped with a 12 volt starter

I hope its not the dual shaft. I have a tecumseh engine out of a leaf vacuum with that setup and needless to say it is in pieces in my barn. I can get the predator for 300$ with the starter.

I got fed up with my Tec hm100. I put the HF 13 hp on it and it is awesome. I mounted the Battery on the back.

How does your machine throw snow. My Predator 212cc is a beast and even 5 years later it still runs great. Here is is throwing 11 inches of snow.

I know this is an older thread but ran into something the other day that may be of use to someone. Watch the engine footprint of whatever you select. I looked at using a LCT 291 on a Craftsman (Murray) Driftbuster 10-32 and the front surface of the engine blocks off the control for auger/drive controls (meaning you have to permanently remove those controls to fit the engine). It's not insurmountable as I know how I can fix it to make it work, but be sure to check it all out to avoid surprises. know what you have and need before putting out your $$.


Just a comment.

Depending on your money, time, and enthusiasm, to solve the spark problem, I'd try an after market ignition market like Mega Fire for $15. Check the ground, sand the magnet.

1995 Murray Craftsman 10hp, 29" w. 12" impeller
A 1983 Real John Deere 10hp, 32" w. 12" impeller, 16" auger, 20" high front, cast iron gear box, chains
Noma 9hp, 27" w. 12" impeller
Noma 5hp, 24" w. 12" impeller, 20" high front
Gravely Convertible, 12hp Kohler cast iron, 26" width, 600 lbs of cast iron & steel, 2 speed impeller, 4 ground speeds
Dynamark 8hp, 26", 12" impeller, for sale
Several other 5hp, 8hp, several 2 cycle, all for sale

Good points. Another thing you can check, this works well if you have a gas-line shutoff. disconnect the ground wires off the throttle and on-off switch and try it. I've seen them go bad in the past. You can kill the engine this way by shutting off the gas and let the carb go dry, or if you're adventurous ground out the plug wire on the spark plug (that's the way it used to be done, just use something insulated or you'll get the shock of your life). Also look at the wire than runs under the flywheel for any open spots on it too.

As HCBPH stated, definitely check the ground wire at the throttle FIRST. Disconnect it from the throttle then check the spark plug for spark, if not, then check the ignition coil magneto for a good ground, sand the flywheel magnet, you can even check the magneto for the correct ohms.

I put one of those mag fire thingies on my machine, and it works great. Just make sure that it has a non kickback feature. Because that can really hurt.
