Tecumseh hs50 performance upgrades???

[99JT]

Picked up a 79 toro snowblower in amazing condition that I'm going to restore, get everything powder coated, new chrome, zinc plating all of them original hardware and all.

Trying to figure out what's worth doing to the engine for performance and reliability not sure if getting the cam reground is with it but kinda thinking a billet rod is probably a not a bad idea.
So far I Ordered a .042" copper head gasket to see how it likes the higher compression, can always get the head milled later if it leaks, cleaned up the intake and exhaust ports, and the block is going to the machine shop tomorrow to have the valve seats cut and guides replaced as the intake one is completely, exhaust isn't as bad but still not great.

This might be a good resource. Since you’re just running the engine in a blower, it’s going to run at constant governed rpm and shouldn’t need something like a billet rod.

Is this motor staying in the blower or going on a bike? even with mods this motor still wont compare to a larger displacement blower like a 10 hp tecumseh. They are in a leage of there own but more power can be acheved. how far are you looking to go? also ! quick easy mod for a quick free gain. Tecumseh and briggs 5hp and carbs only open the butterfly 3/4 of the way in stock form, fix that and free extra horsepower (Its a noticable boost).

personally i like the Tecumseh HS50 engines, as they fit most mini bike frames nicely. and they are readily available, and tend to be inexpensive. again i like the pre-1980 version. there's a lot you can do to get good power from them. http://www.pinrepair.com/minibikes/tecumsehmb.htm
