Predator engine questions

Ok well a coworker is giving me his old yard machines 24" but what he thought was a 8hp turns out to be a tecumseh 5hp which I'm oh so familiar with, he put a new carb on it but said he could never get it to run right again, Now my delema, It's supposed to be in real good shape always garaged and even has the paperwork he got when he purchased it, BUT my 22" Snapper has a Tecmseh 6hp and struggles on the snow banks so I'm thinking if the Yard Machines (YM) struggles but is in good shape I might go with a predictor engine, my big question is how much will I have to mod for the engine swap, Roughly how much different location wise will the drive shaft be, I'm guessing a different length belt, Can't say I've ever swapped a engine for a different engine design before, but the extra HP for $100 will be nice and a decent running 24" snow blower for $100 can't be beat, Just hope it's in as good condition as he claims, I might have it tomorrow, if so I'll post up pics.

Thanks
Dauntae

Is the 5HP a single shaft Tecumseh?
You can get some drawings showing shaft height and such from the pdf file at harbor freight if you want to compare with your Yard Machine. The dimensional drawing are towards the back

There is also an issue often with the chute crank location when going from an L-head to an OHV Honda Clone

Not sure on the yard machines yet, We live in opposite directions from where we work so it would be better than a hour drive to his house so he's bringing in to work when he can get his son to help him load it in his truck, Then load it into mine in the parking lot lol Hopefully he'll have it tomorrow and I'll know which model and engine it is. For the crank, I can get very creative in making things work, Have full access to the manual machining Dept at my job so fabricating stuff is my fun time.

I've done over 20 predator 212cc engine swaps on ariens 24" machines and 1 troy Bilt, plenty of power for a small machine. If it's a 5hp single shaft your swapping out I'd say all you will need to modify is longer 5/16 - 18 engine mounting studs, and possibly control rod for chute rotation. It should have the same 3/4" crankshaft size. What part of MA you from?? I could help you with your project, I have complete hobby shop at home. I am really close to Pelham / Tyngsboro line. Let me know what you need help with and I'll get it done with ya.

Thank you for the offer Shaw, I'm in New Bedford so a little ways off, I'm going to see how it works with the 5hp first if I get it running so it will be a little time before I do the switch if it needs it, If it's in good shape that is. Want one to keep with a little power but may just hold on to my old Snapper 6/22 for a while for a backup, I do have a single stage also but that's having some starting issues and I'm beginning to think it may be the valve gap but I'll tear into that one at a later time.
