3 hp dynamark snow thrower

Good day- I bought a non running 3hp dynamark snow thrower. After some checking, my suspecion was correct. The carb was clogged with old oil from the 2stroke gas that was left in it.

It will run for a couple of seconds on ether. I pulled the carb and the bowl was full of old gas and oil. I drained the tank and replaced it with fresh gas oil mix. I soaked the carb in cleaner and blew it out. It still will not run more than a few seconds on ether.

I cannot tell what the brand of the motor or carb is in order to buy a new carb for it. I've done some research but cannot come up with a carb part number. There are several on eBay for 3 hp motors, how do I know which is the correct one? Any help is appreciated. I can post a pic of the snow thrower if I can figure out how

How long did you soak the carb in cleaner?

If there's a long narrow passage that's clogged with "guck", it may take quite a while for the cleaner to get in there and dissolve it. Many hours, or even days.

Also pics of the snowblower would probably help, as well as pics of the engine. And any model # info for the machine and engine.

~1994 Ariens 924084 (ST1032) "papa bear": restored, re-engined, real nice!
1991 Ariens 924050 (ST824) "mama bear"
Toro PowerCurve 1800 "baby bear"

Be alert! America needs more lerts.

It's likely a Tecumseh . There are tons of Tecumseh 3hp, Powerlite, Tec 98cc carbs on Ebay or Amazon for cheap.

Follow your green wires from the key switch, one will go behind the cowling and one is attached to the outside of the recoil housing. You should notice the engine model sticker around where that wire is attached. (HSK600 or TH098SA)
