1 inch pully setup

I may be doing a re-power soon. I got a free MTD 5-24 that is in REALLY nice shape. FREE! Of course, it has a 5HP Tec. The body/mechanics are in really good shape, like new, but I don't know about the engine.

The spark plug wire is gone. Just gone. So I ordered the new module. The spark plug was missing so it was sitting under a deck with nothing to stop crap from getting in the hole. I pulled it, it seemed pretty good, it spun free anyway.

Ok, all that aside. I'm thinking if I have to re power it, I'll go to the 8HP Predator. The biggest problem is the 8HP has a 1" shaft, the 6.5 has a 3/4 shaft. Is it easy enough to get a pulley setup for 1 inch shaft, or should I just screw it and go with the 6.5?

I'm giving this machine to my son, who's 15, to go clear some sidewalks and make some money for himself. I'm also making him do all the work to fix it. More of a life lesson than anything else. My thinking is a bigger engine will help with EOD type stuff, and teach him to work around problems.

6.5 is plenty of motor for a 24" bucket.

Agree with Jack Mels, 6.5 is all you need, save the money and installation problems. The Predator is a big horsepower boost over the Tecumseh 5. I always felt 24" is to wide for those heavy wet snows for a 5hp.

yup a new 6.5hp engine should do the job perfectly. i never got to use my machine when it had the factory 5hp engine but it has always done good with the 6.5 that is on it.

OOPS, it's a 22 inch machine. My old one was 24 inch, but it was otherwise EXACTLY the same.

I'll stick with the 6.5 for now if I can't get it running. Should the 6.5 be re-jetted for cold weather? If so, to which jet?

First things first get it running, then check for a lean condition.
