Sno-tek 920404 gets a new/bigger engine

Years ago I bought a 24" Sno-tek from HD. It was a promotional ad. This particular model comes with a 136cc lct engine. I bought it just before a snow storm. The thing never really ran right. Brand new out of the box it always surged. This fall I started it up and then it quit altogether.
Picked up a 212cc harbor freight engine. They had one of the higher performance 212cc engines.
I installed it last week.

There are two pullies on the shaft. The pulley closest to the engine was at first hard to get off. A crow 3' crow bar would not take it off. What did take it off in seconds was a harbor freight bearing puller, a 1/2" impact air wrench, a compressor and WD-40.

The 4 bolts on the housing match up perfectly with the new engine. No drilling or mods needed. The best part is that the new engine only cost $99.

There was one very small issue. On the end of the shaft a bolt comes out. That bolt will not fit on the new 212cc engine....it is to big. Get your self a bolt of the same length, fine thread but a bit skinnier (a quick Google search will tell you the size b/c I forgot) and it will hold the second pulley on and the first as well.

Did you transfer the nice mitt sized pull cord handle over to the Predator ??

You're going to love the smoother running more powerful engine.
Now you just need to put the old 136cc engine in the classifieds to help pay for the Predator.

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

I filled the new engine with non-ethanol high test gas. New engine started on the 3rd pull. More importantly it ran right.

I would suggest changing the oil. The oil in the new engine didn't look the best and so I drained what was in there (there wasn't much but what was in there didn't look right) and added new oil.

I hope this helps the family guy who might be on a budget or who enjoys saving money. A $99 dollar engine vs buying a new blower is a no brainer for me. I could have bought a 5k blower but I figured the new shine would wear off quickly.

Side note: Not all harbor frieght predator 212cc engines are created equal. There are differences out there.
There are plenty of modifications that can be made to these engines: rpm limiters can be taken off, muffler mods and spring rates to name a few. I have projects piled up that require my attention so I left the engine as is.

In a week or so, I'll add chains to the tires but that will be about it.

No snow deep enough to blow yet but I'll reply after a few good snow storms.

@ Kissafrog. .....

I knew what was wrong with the old LCT engine. It was leaking gas from the carb.

I gave the old engine away to a new guy at work who has 3 kids. I should have transferred the big handle but didn't think of it at the time. That was a good suggestion. I am sure the new guy will have fun playing with the old engine....maybe he can make it into a father/son project.
