Replace Powermore with Predator 212 cc

I have a 2008 troy bilt , 24" model 2410 snow blower and the engine is defective. What do I have to do to mount the predator 212 cc Harbor Freight engine?

There's plenty of posts about re-powering with the 212cc engine. I've not done it myself, but I would imagine looking at the engine you currently have and taking a few measurements of things like the diameter of the shaft, how high the shaft sits it sits from the snowblower frame, would be a good place to start to compare to the 212cc. Other than that, I would think the bolt pattern is pretty much standard. You can probably find those numbers online to compare them.

Maybe others will have some better information for you, but I would almost bet it would be a straight swap.

I'm pretty much retired from the forum thing, but I check in every now and then.

they are pretty much the same motor in terms of dimensions. i think you have to use 3/4 bore pulleys on the predator

What made it defective, just curious. I've never done it on a machine newer than 1983, I'd imagine it would be relatively straight forward swap on yours.

I ran over to Harbor Freight today and took some rough measurements,,the predator 212 crank is about 4" vs 5" Powermore off the mounting deck, The pr. crank is 3/4"dia vs 7/8" pm., the pr. crank is 2 3/8" long vs the pm. 2 7/8(pr. about 1/2" shorter), mounting bolt location are about the same.

I am still trying to save the present Powermore engine. I was blowing snow last week and it just stopped and would not restart?? So, I have done the following to no avail, changed gas, checked the valve lash, ok; pulled the tank filter,ok; cleaned the carb, ok; put on a new carb; changed the spark plug, it had a weak spark, tested it with a plug checker; put on a new coil harness, lots of spark; pulled the head to check lash, push rods and valve seating. I am putting it back together now?? any ideas

I don't see how you could have missed anything at this point then? If it has good compression, good spark (timed right), and the fuel is getting there - you need to make sure that it's not getting grounded or something silly when your starting it. Something has to be either no fuel or no spark at that point....?




I am deathly allergic to shovels!

Well, the snow blower is running today. After all of the changes the issues was the Valve lash was too tight on the intake valve. I opened the intake valve lash another .002 to .005 and it took off running with no surging issue. I guess this Powermore engine is very sensitive to valve tolerance??? Still seems strange that the Snow blower was running when it stopped for this valve issues? But I will take it. I put my baby in the yarding storage shed until November 16. Thanks for your input.

Might have been the weak spark that killed it and later the lash that prevented it from starting back up


Just in case you do need to re-power Storm2410 did a great job installing a Predator on his. Said he was able to use all the hardware only needed to get a 7/8 to 3/4 adapter off ebay.
Looks like OEM.

Make sure the windows are up before the snow plow goes by !!

The Tecumseh flat heads will sometimes run fine when cold and then stall when they get hot. As the valves heat up the metal expands and they no longer close fully. With the loss of compression the engines loose power and can eventually stall.

Your Powermore OHV might have had something similar happening.

Please direct all snow blower questions to the forums and not to me with PMs.
